PHILADELPHIA (CBS) — Authorities have recovered dozens of guns from a home in the Bustleton section of Philadelphia. Police say they were called to a home on the 9700-block of Northeast Avenue for reports of a suicidal man.

The 72-year-old homeowner is now undergoing a mental health evaluation.

Police say they recovered handguns, rifles, assault weapons, grenades, an apparent pipe-bomb, and a jar of mercury which is a hazardous material.

Investigators say the homeowner may have been a gun dealer in the past.
