About 100 firearms were stolen from a home in a Philadelphia suburb last Friday according to a document obtained by CBS News.
The victim, a resident of Chester, PA, told police that approximately 100 guns including various calibers of semiautomatic pistols, revolvers, shotguns, and rifles were taken during the burglary, according to a Delaware County officer safety advisory.
The advisory warns police in or near the City of Chester and Delaware County to use "extreme caution" due to the significant number of firearms stolen in the burglary.
The Pennsylvania State Police firearm sale database confirms the victim has purchased at least 50 handguns including .32, .380, 9mm, .40 and .45 caliber semi-automatic pistols.
The victim, however, did not allow investigators to inspect his home after the burglary, so the exact number of stolen weapons remains unknown, according to the officer safety alert.
The Chester Police Department said it is investigating the break-in and notified the ATF of the burglary.
A spokesperson for the ATF Philadelphia Field Office said they do not know the exact number of firearms stolen from the home though it is believed to be less than the victim's claim of 100.
The spokesperson added the ATF is working to recover the weapons so "they don't end up in the hands of criminals."
