Old man busted in Philly for owning ‘arsenal,’ including bombs

Authorities have launched an investigation in the Bustleton section of Philadelphia after police found a large cache of weaponry inside a home on Wednesday night.

The madness is unraveling on the 9700 block of Northeast Avenue.

Police say they encountered a 72-year old man whom relatives expressed concern that he may be depressed and or suicidal. The man was taken to the hospital for evaluation.

Police say family members gave them the authorization to enter the home, and upon entering, they found more than 50 guns, hundreds of rounds of ammo, 10 hand grenades, a pipe bomb and liquid mercury. The grenades are believed to be inert.

This is a developing story.
