Probable Cause and Hot Pursuit: When Police Can Make a Warrantless Arrest

The Constitution guarantees every person the right against unreasonable searches and seizures. But this right is not absolute. In People v. Leng Haiyun (G.R. No. 242889, March 14, 2022), the Supreme Court explained when police officers may validly arrest a person without a warrant, and what happens to evidence seized during such an arrest.

The Facts of the Case

On May 28, 2013, a gasoline boy at a station in Pasuquin, Ilocos Norte reported to police that someone from a silver Toyota Previa had broken two bottles at the driver's side, alarming station personnel. Police officers immediately responded and went to the gasoline station.

When the occupants of the Toyota Previa saw the police, they fled toward the north. The police chased them and coordinated with officers manning a COMELEC checkpoint to intercept the vehicle. When the vehicle stopped, an officer approached and saw several loose plate numbers on the floor behind the driver. The occupants, four Chinese nationals, could not present passports or travel documents.

The officers invited them to the police station. While the occupants were alighting from the vehicle, the officers saw in plain view the butts and barrels of several firearms under the second-row seat. A subsequent search yielded high-powered firearms, ammunition, hand grenades, and explosives.

The Issue

The central question was whether the warrantless arrest of the accused was valid, and consequently, whether the evidence seized was admissible in court.

The Ruling: A Valid Warrantless Arrest

The Supreme Court ruled that the warrantless arrest was valid under Section 5(b), Rule 113 of the Revised Rules of Criminal Procedure, which allows a warrantless arrest when an offense has just been committed and the arresting officer has personal knowledge of facts and circumstances indicating that the person to be arrested committed it.

The Court clarified that the arresting officer need not have personally witnessed the commission of the offense. What matters is that the officer's suspicion is based on actual facts—circumstances sufficiently strong in themselves to create probable cause.

In this case, the following circumstances supported probable cause:

• The police received a report of the bottle-breaking incident and immediately investigated;
• The accused fled upon seeing the police;
• The police chased the vehicle and intercepted it at a checkpoint;
• The officer saw scattered plate numbers and the occupants had no travel documents.

The Court also noted that the bottle-breaking could constitute unjust vexation—a crime broad enough to include conduct that unjustifiably annoys or vexes another person.

The Plain View Doctrine and Search Incident to Arrest

The Court also upheld the seizure of the firearms and explosives under two doctrines.

First, the plain view doctrine. The officers saw the firearms in plain view while the occupants were lawfully alighting from the vehicle. The doctrine applies when the officer has prior justification for the intrusion, the discovery is inadvertent, and it is immediately apparent that the item is evidence of a crime or contraband.

Second, search incident to a lawful arrest. Under Section 13, Rule 126 of the Rules of Court, a person lawfully arrested may be searched for dangerous weapons or anything that may be used as proof in the commission of an offense. The search may extend to areas within the arrested person's immediate control—which included the vehicle.

Practical Takeaways

• Personal knowledge does not mean eyewitness testimony. Police officers may rely on reports, investigations, and observed behavior to establish probable cause for a warrantless arrest.
• Flight is a significant factor. When a person flees upon seeing police officers, that conduct can strengthen probable cause for arrest.
• Immediacy matters. The arrest must follow closely after the offense was committed and the investigation conducted.
• Plain view seizures are valid. If officers are lawfully present and inadvertently see contraband, they may seize it without a warrant.
• A valid arrest authorizes a limited search. Officers may search the arrested person and areas within their immediate control for weapons or evidence.
