The UBC Okanagan student who was dragged handcuffed down the hallway by an RCMP officer is worried that it’s too late.

RCMP say the two men captured on surveillance video may have information that’s important to the police wellness-check investigation.

After receiving no answer at the door, officers forced entry into the home and found the man already dead.

RCMP say the review by Abbotsford police into the conduct of a police officer during a wellness check has been returned to the B.. C. RCMP for further investigation.

"We want the truth out to the public -- what happened to him, how (our) family's been doing," said Kyaw Din's sister.

A West Kelowna woman has filed a second lawsuit against the RCMP officer who dragged a UBC Okanagan nursing student down a hallway during a wellness check.

Rallies are scheduled for Vancouver, Kelowna, Surrey and Richmond for the B.C. nursing student who was handcuffed, dragged and stepped on during an RCMP wellness check.

Surveillance video showing an RCMP officer dragging a UBC Okanagan nursing student down the hallway during a wellness check has drawn attention to how mental health is handled within the police force and prompted a former Mountie to speak out.

Last month, disturbing video was released of university nursing student Mona Wang being dragged while handcuffed during a mental-health wellness check.

During a rare press conference Thursday morning, RCMP Southeast District Chief Supt. Brad Hougli said he was “deeply concerned” when he saw a surveillance video showing part of a wellness check conducted by an RCMP officer.
