People v. Haiyun

Summary

Four Chinese nationals were convicted for illegal possession of explosives and violation of election gun ban after being arrested during the 2013 election period in Ilocos Norte. The Supreme Court upheld their conviction, ruling that their warrantless arrest was valid under the 'hot pursuit' provision of Section 5(b), Rule 113, based on a confluence of circumstances including a bottle-breaking incident at a gasoline station, their flight upon seeing police officers, and discovery of multiple suspicious items. The Court found that the seized firearms and explosives were admissible evidence under the plain view doctrine and as search incident to lawful arrest. The accused-appellants were sentenced to reclusion perpetua for illegal possession of explosives and 2-5 years imprisonment for the election offense. The case establishes important precedent on warrantless arrests requiring probable cause based on personal knowledge of facts and circumstances, and the validity of searches conducted under the plain view doctrine during lawful police operations.
