The chief of the Victoria police was not injured in what the department has characterized as an "assault".
It occurred when Chief Del Manak was attending a memorial for Chantal Moore, an Indigenous woman shot last year by police in Edmunston, New Brunswick, during a wellness check.
According to Victoria police, a woman poured a liquid on Manak, which was captured on video. Manak was at the memorial at the B.C. legislature on the invitation of Moore's mother.
"Officers in the area then approached the suspect," Victoria police said in a news release. "At that time a group surrounded the suspect and then surrounded officers. Five people were taken into custody."
Police say it's not believed that those arrested were involved in organizing the memorial event.
The names of those arrested have not been released.
Manak spent the early part of his career as a Vancouver police officer before joining the Victoria Police Department in 1993. He became the chief in 2017.
