PHILADELPHIA (WPVI) — Residents in Philadelphia’s Fishtown neighborhood are on high alert after packages were stolen from the mailroom of an apartment building.

It happened on Thursday around 18:00.

Surveillance video shows the suspects breaking into the building and digging through several boxes in the mail room.

According to the property manager, the suspects used a USPS email key.

“It’s not really just a concern for us, it’s a concern for every building in the area that a key gives access to. I don’t know how many units could be hit,” said property manager Jorden Leibowitz.

Authorities say the postal inspector is aware of and is investigating this incident along with the Philadelphia Police Department.

Anyone with information about this incident or who may recognize the suspects is asked to contact police.
