Police in Surrey were kept busy overnight Saturday and into Sunday, responding to multiple calls, including reports of a drive-by shooting Sunday morning.

Officers taped off several blocks near 92nd Avenue at roughly 7:30 a.m., after receiving several calls about shots being fired in the area. Witnesses claimed to have heard as many as seven shots, and officers could be seen recovering shell casings from the scene.

Police have not released any information about the shooting, or whether there was a victim.

The busy night began at around 1:30 a.m., when officers responded to reports of an assault near 180th Street and 64th Avenue. Witnesses told CTV News a teen was attacked with a knife and suffered a cut to his head.

An hour later, police responded to another reported assault, this one in Whalley, across from Surrey Central SkyTrain Station, where a man was found lying on the ground unconscious. He was taken to hospital and police could be seen taking one person into custody.

Surrey RCMP also responded to reports of a woman calling for help in the parkade at the Sheraton hotel on 104th Avenue, where witnesses say the woman was seen with a broken nose and a black eye.

She was transported to hospital, and police arrested one man at the scene.

Surrey RCMP did not respond to requests for comment on any of these incidents.
