Vancouver Police Department Sgt. Randy Fincham says traffic will continue to be impacted along Knight Street between Kingsway and E. King Edward Avenue for several hours Thursday night.
Officers are trying to negotiate the surrender of the occupants inside a home in the 3900 block of Knight Street, he said.
Police dogs have been brought out and officers could be heard issuing warnings that they will use force if the occupants don't come out on their own.
Fincham said the home is subject to a search warrant that officers tried to execute earlier this evening.
