Two masked gunmen burst into a restaurant early Thursday and sprayed it with bullets, killing two people and injuring six, police said.

Police said they were called to the Fortune Happiness restaurant in a neighborhood frequented by drug dealers and prostitutes. By the time officers got there about 4:30 a.m., the gunmen had fled.

"Members arrived to a chaotic scene at the restaurant with tables and chairs overturned, customers shot, broken glass and frantic witnesses," a police statement said.

Police did not comment on a motive, but suggested it was not a random shooting.

"Typically we'll see things like this and it would indicate to us that it's a targeted hit," said Constable Howard Chow.

Of the six injured, one was hospitalized in critical condition, Inspector Bob Chapman said

The windows in the front of the restaurant were blown out. Chapman said there were 9 mm and .45-caliber shell casings on the floor.

The CTV television network quoted witnesses as saying one gunman entered from the back of the restaurant, the other from the front.
