US police in Philadelphia are trying to find a man who fired into an Asian food store and wounded three people on Tuesday night.

Investigators have released a surveillance video of the crime on YouTube.

The video, which features images from inside the store as well as from a camera outside, shows a man in grey walking up to the store and firing a shot through the glass front door.

Several young men are seen scrambling to hold the door shut from inside.
