The Independent Investigation Office (IIO) is looking for a key witness in the incident that involved the death of a man in Langley on Wednesday morning.
On Friday, the IIO announced that investigators want to speak to the driver of a light-coloured SUV, which was travelling eastbound on 72nd Avenue at about 3:22 a.m. on Oct. 23.
The SUV made a right hand turn onto 208A Street.
The IIO is asking for this witness, and anyone else who may have seen, heard, or recorded the incident, to contact the IIO Witness Line at 1-855-446-8477.
The incident began with an abandoned 9-1-1 call just after 3 a.m., according to the regional E Division RCMP.
After attempts to call back the number were unsuccessful, Langley RCMP were sent to the location. Officers found one man who appeared to be under the influence of drugs. When they tried to take him into custody, some sort of physical altercation occurred.
After he was arrested, the man appeared to be losing consciousness, and Emergency Health Services were called in, and officers performed CPR until firefighters and ambulance arrived at the scene.
The man was later pronounced dead.

All deaths involving police actions in B.C. are investigated by the IIO, an outside agency.
