Canadian Mountie is seen dragging a semi-conscious nursing student face-first down a hallway before she stomps on her head and picks her up by the hair during a welfare check (11 Pics)

A nursing student alleges she was kicked and punched at the hands of an Royal Canadian Mounted Police officer after her boyfriend called emergency services to request a health check.

Lacey Browning is seen on surveillance footage dragging Mona Wang down a carpeted hallway of her apartment building in British Columbia, Canada on January 20 while she was semi-conscious, then stomping on her head and dragging her by the hair.

She claims Browning was physically abuse when she told her she couldn't stand up to leave the apartment where cops say she was found lying on the floor with a box cutter in her hand and empty bottles of acetaminophen, melatonin and wine nearby. 

Surveillance video that surfaced as part of the lawsuit filed with the court June 15, naming Browning, Canada's attorney general and British Columbia's minister of public safety and solicitor general as defendants.

The defendants say the officer found Wang lying on the floor with a box cutter in her hand and empty bottles of acetaminophen, melatonin and wine nearby. She is pictured left in an image she posted on Instagram in April

'Browning proceeded to assault the plaintiff by stepping on the plaintiff's arm,' the lawsuit states. 'Browning kicked the plaintiff in the stomach while the plaintiff was lying on the bathroom floor semi-conscious.'

She posted images of the injures on social media 11 weeks ago when she was still waiting for the video to be released.  

Cops claim Wang - who is seen in the video wearing a bra and leggings - was found bleeding with lacerations on the chest and upper arm.

A response to the lawsuit alleges that the student began yelling and swinging her arms at Browning, who proceeded to strike Wang with an open palm to subdue and arrest her under the Mental Health Act. 

The defendants assert that Wang was a risk to herself and others, was begging to be killed and swore excessively.

The defense insists Browning used no more force than was reasonable and necessary.

Wang, who studies at the University of British Columbia's Okanagan campus in Kelowna, claims she suffered cuts, bruises and a swollen eye as a result of the alleged assault. She was taken to hospital.

The hallway video was filmed after Browning handcuffed Wang. Browning appears calm and smiling as witness go in and out of the lobby but is seen handling her roughly when it appears no one is around. 

Wang says after taking pills and wine she had a panic attack and was drifting in an out of consciousness. 

She told CTV News that she 'wasn't really in a great state of mind' and was hyperventilating but the cop told her to 'stop being dramatic'.

Wang says Browning did not attempt to assess whether she needed medical assistance. The building video released this month by court order is not accompanied by audio.

Wang claims the cop punched her, causing her to blackout. 

'The plaintiff has suffered emotional distress, humiliation, shame, and embarrassment, psychological and emotional trauma,' says a statement of claim filed March 26 in British Columbia Supreme Court.

Wang said she faces combative patients everyday as a nurse so the police can't justify their rough handling.

The cop is on administrative duties but Wang wants her fired. She is pictured in medical care

'I just don't understand why she felt the need to have to drag me into the lobby where everyone can see me in the middle of winter, right, and I didn't have a shirt on, I didn't have my shoes on,' Wang told CTV.

'And I was just calling for help. It was quite difficult for people that I see on a daily basis walking past, seeing me in such a vulnerable state. 

'I definitely think that when police get in a situation like that their instinct is to use violence.'

RCMP spokeswoman Sgt. Janelle Shoihet would not release the identity of the officer in the video, but said the Mountie is on administrative duties. 

In an email, Shoihet says an internal investigation is underway, and the Mounties will ask an outside police department to review the findings.

Four people have died in Canada at the hands of police responding to mental wellness checks since April.
