Dramatic video of US shooting

Police in the US have released a dramatic surveillance video of a triple shooting in Philadelphia in an attempt to identify the gunman.

The shooting took place on Tuesday night at Chinese food store when a gunman walked up to the front door and fired shots at people inside.

The footage shows one of the victims struggling to keep the suspect out of the store by holding the door closed.

After several failed attempts to enter the store the suspect proceeds to fire at least five shots through a glass door.

The gunman then appears to run out of ammunition and departs the scene.

Fortunately, no one was killed in the shooting.
