People of the Philippines vs. Sucro

A warrantless arrest is lawful when the person to be arrested is caught in the act of committing an offense in the presence of a peace officer, and evidence seized as a consequence of such a lawful arrest is admissible.

Police officers in Kalibo, Aklan, conducted a surveillance operation on accused-appellant Edison Sucro based on information that he was selling marijuana. During the operation, an undercover officer observed Sucro conduct multiple drug transactions near a chapel. After a buyer was intercepted with marijuana and identified Sucro as the seller, the police arrested Sucro without a warrant and recovered additional marijuana from a cart at the scene.

• Surveillance Operation: On March 21, 1989, Pat. Roy Fulgencio, acting on orders from his station commander, positioned himself to monitor the appellant's activities near a chapel in Kalibo, Aklan.
• Observation of Transactions: From a distance of about two meters, Pat. Fulgencio saw the appellant repeatedly enter the chapel, retrieve items from a cart, and hand them to individuals on the street. These activities were reported via radio to the police team.
• Interception of Buyer: A police team intercepted a buyer, Ronnie Macabante, who threw a tea bag of marijuana to the ground upon seeing the officers. Macabante admitted he had just purchased it from the appellant.
• Warrantless Arrest and Seizure: The police then arrested the appellant without a warrant at a nearby street corner. They recovered nineteen sticks and four tea bags of marijuana from the cart inside the chapel. Laboratory tests confirmed the substances were marijuana.
• Defense's Version: The appellant interposed the defense of alibi, claiming he was elsewhere distributing campaign handbills for a relative.

• Illegality of Arrest and Seizure: The appellant argued that his arrest without a warrant was illegal because the police had prior information and sufficient time to secure a warrant. Consequently, the evidence (the marijuana) seized as a result of that arrest was inadmissible as the "fruit of a poisonous tree."
• Credibility of Prosecution Witness: The appellant assailed the credibility of the buyer, Macabante, suggesting his testimony was motivated by a desire to escape prosecution.

• Validity of Warrantless Arrest: The State countered that the arrest was lawful under Section 5(a), Rule 113 of the Rules on Criminal Procedure, as the appellant was caught in flagrante delicto—committing the offense of selling marijuana in the presence of the arresting officers.
• Admissibility of Seized Evidence: The Solicitor General argued that the marijuana was seized as an incident to a lawful arrest, pursuant to Section 12, Rule 126 of the Rules on Criminal Procedure, and was therefore admissible.
• Probable Cause for Surveillance: The State maintained that the police acted on probable cause based on reliable information, and the subsequent surveillance provided them with personal knowledge of the crime's commission.

• Validity of Warrantless Arrest: Whether the warrantless arrest of the accused-appellant was lawful.
• Admissibility of Evidence: Whether the marijuana seized from the appellant and the scene was admissible in evidence.
• Sufficiency of Evidence for Conviction: Whether the evidence presented by the prosecution was sufficient to prove the appellant's guilt beyond reasonable doubt.

• Validity of Warrantless Arrest: The warrantless arrest was lawful. The police officers had personal knowledge that an offense was being committed in their presence, as they directly witnessed the appellant's drug transactions during the surveillance operation. This falls squarely under the exception for in flagrante delicto arrests.
• Admissibility of Evidence: The seized marijuana was admissible. The search was conducted as an incident to the appellant's lawful arrest, which permits the seizure of evidence related to the offense. The argument that the police should have secured a warrant beforehand was rejected, as the circumstances justified the warrantless action.
• Sufficiency of Evidence for Conviction: The evidence was sufficient for conviction. The positive identification of the appellant by the buyer, corroborated by the testimonies of the police officers and the forensic chemist's report, established the elements of the crime. The defense of alibi could not overcome this positive identification.

• In Flagrante Delicto Warrantless Arrest — A peace officer may, without a warrant, arrest a person when, in his presence, the person to be arrested has committed, is actually committing, or is attempting to commit an offense. The Court applied this by finding that the police officers personally witnessed the appellant selling marijuana during their surveillance, thus making the arrest lawful.
• Search Incidental to a Lawful Arrest — A person lawfully arrested may be searched for dangerous weapons or anything that may be used as proof of the commission of an offense, without a search warrant. The Court relied on this doctrine to uphold the admissibility of the marijuana seized from the appellant and the chapel cart following his lawful arrest.

• "An offense is committed in the presence or within the view of an officer, within the meaning of the rule authorizing an arrest without a warrant, when the officer sees the offense, although at a distance, or hears the disturbances created thereby and proceeds at once to the scene thereof."
• "The non-filing of a complaint against him for possession of marijuana may have been the reason of his willingness to testify in court against the accused. But this does not necessarily taint the evidence that proceeds from his lips."

• People v. Bati, G.R. No. 87429 (1990) — Cited as controlling precedent to establish that police officers who conduct surveillance and directly observe a drug transaction have personal knowledge of the crime, justifying a warrantless arrest.
• People v. Lo Ho Wing, G.R. No. 88017 (1991) — Applied by analogy to show that probable cause based on intelligence reports and surveillance can justify warrantless action, even if insufficient for a search warrant.
• U.S. v. Fortaleza, 12 Phil. 472 (1909) and U.S. v. Samonte, 16 Phil. 516 (1910) — Cited to define when an offense is considered committed "in the presence" of an officer.

• Section 5(a), Rule 113, Rules on Criminal Procedure — Provides for a lawful warrantless arrest when the person to be arrested is caught in the act of committing an offense in the presence of a peace officer. Applied to validate the appellant's arrest.
• Section 12, Rule 126, Rules on Criminal Procedure — Allows the search of a person lawfully arrested without a warrant for proof of the commission of an offense. Applied to justify the seizure of the marijuana.
• Section 4, Article II, Dangerous Drugs Act (Republic Act No. 6425, as amended) — The substantive provision under which the appellant was convicted for the illegal sale of marijuana.
