Authorities are looking for a group of men who staged a violent robbery at a Dunkin' Donuts in Delray Beach.

Police spokesman Jeff Messer says four people were shot Wednesday night but are expected to recover.

Witnesses say as many as four armed men burst into the cafe and ordered customers to get on the floor. Police say the suspects went through customers' pockets and cleaned out the store's register. As they were leaving, a suspect fired a shotgun, hitting three customers.

The fourth victim was a motorist who got shot after flashing his high beams at the suspects when they ran in his path. Authorities searched the area for hours overnight but did not find any of the suspects. They're offering a $5,000 reward for information that could lead to an arrest.
