An officer has testified he faced a "chaotic situation" when he responded to a call on Halloween in 2014 that left a woman covered in bruises.

Lana Sinclair is in court today and Thursday after police charged her with assaulting a peace officer and resisting a peace officer. Sinclair says police assaulted her.

Lana Sinclair alleges a police officer slammed her face into her sewing table in her living room, resulting in these injuries. (Lana Sinclair) The first officer to testify said he responded after a 911 call reported an intoxicated woman. He said Sinclair was outside, yelling at her boyfriend and eight-year-old son, when the officer and his partner arrived around 8:50 p.m. CT.

The officer said he went inside with Sinclair while his partner stayed with her boyfriend and son.

The officer testified that he told Sinclair he was going to call Child and Family Services, and Sinclair tried to block the officer from getting her son. The officer testified that Sinclair, with only one hand held by handcuffs, twisted to grab her sewing table, and because she was wearing nylon socks on a laminate floor, she slipped and hit her head on the ground.

He called his supervisor and paramedics and when they arrived, Sinclair claimed the police punched her, the officer said.

The Crown asked the officer if he hit Sinclair with his baton.

"Oh God, no," he responded. Neither he nor his partner poked, pushed or punched Sinclair, he testified.

The defence submitted photos as evidence to court showing bruises on Sinclair's face, arms and legs and asked the officer for an explanation. He responded that Sinclair was wearing long pants and sleeves and was rolling around on her stomach.

Before the trial, Sinclair told CBC that when officers showed up at her home, she yelled, but it was at her son to hurry up and go trick-or-treating.

Lana Sinclair alleges the injuries on her face are the result of police brutality she experienced when officers showed up at her house on Halloween in 2014. She said the officer assaulted her with his baton and then handcuffed her. She alleges he then kicked her feet out from under her, sending her face first into her sewing table, causing the bruises on her face.

Sinclair said her son witnessed that part of the altercation.

Sinclair filed a complaint with the Law Enforcement Review Agency, which investigates complaints about police in Manitoba.

She said she has been unable to teach traditional Indigenous sewing and beading in schools because of the pending charges.
