Police arrested a man at his home on Tuesday for possessing potent explosives and a gun, police said.
A concerned citizen told police at around 2:30 p.m. on Tuesday that a person living on 22nd Street between Valencia and Guerrero was in possession of homemade explosives, according to a police press release.
When officers arrived at the home, the resident, Jerry Lopez, 44, agreed to let them search for explosives. They found 63 explosive devices, the equivalent of approximately 12.5 sticks of dynamite, police said.
Lopez was also in possession of a handgun, which is illegal because he is a convicted felon, according to police. Police established a one-block perimeter while the explosives ordnance disposal team cleared the home.
Lopez was booked at San Francisco County jail and is being charged with one felony count of possession of destructive devices, 63 felony counts of possession of explosives, one felony count of unlawful possession of a firearm, and one count of unlawful possession of fireworks, a misdemeanor.
