The Independent Investigations Office is asking to hear from any witnesses to a Feb. 16 arrest in downtown Victoria, on the wharf in front of the Red Fish Blue Fish food stand.
The IIO, a civilian-oversight agency that investigates police-related incidents resulting in serious harm or death, said the arrest by Victoria police officers happened about 10 p.m.
Two males were arrested, but one resisted and a struggle ensued.
He sustained an injury that has prompted the IIO to get involved.
The IIO said it would particularly like to hear from a person who assisted officers during the incident.
Contact the IIO witness line at 1-855-446-8477.
