A man, who reportedly ran amuck on Saturday, was arrested in Muntinlupa City (Metro Manila) on the same day. Director Joel Pagdilao, National Capital Region Police Office (NCRPO) chief, said Ryan Alcantara yielded a .45 cal. pistol with six bullets during the arrest. He reportedly pointed his gun at some residents before firing three shots in the air during a Christmas party in Barangay Alabang. He is facing charges of alarm and scandal, grave threats and illegal possession of firearms.
