The police are investigating an active shooter situation reported at a mall in Pennsylvania.
A witness at the Lehigh Valley Mall shared a video online, showing apparently a SWAT team running while multiple gunshots are heard in the background.
Following the report, about three dozen police cars and at least four ambulances were sent to the mall, according to The Morning Call.
It is unclear at the moment if the shooter is still hiding inside the mall or has run from the premises.
