Police are looking for three robbers who held up a Seattle grocery with a shotgun and hit one of the employees to get into the safe.

Police say the men were wearing hooded sweatshirts when they entered the Grocery Outlet store before 7 a.m. Friday, before it opened for business.

They forced employees into an office and forced them to open a safe. One employee was struck in the face.

The robbers fled in a waiting car.
