Sentencing hearing to resume for officer with history of violence, 2 years after conviction

The sentencing hearing for a Calgary police officer convicted of assault resumes Monday after it was derailed earlier this year when the Crown's key witness broke down, telling the judge his PTSD had been triggered by the anxiety of testifying.

Trevor Lindsay was a constable with the Calgary police service until he quit last September.

More than two years ago, Lindsay was convicted of the 2015 aggravated assault against Daniel Haworthwho suffered a fractured skull and brain injury when, while handcuffed, he was thrown on the ground headfirst by the officer.

Lindsay has not yet been sentenced for that crime.

• Victim of police violence believes mistreatment racially motivated, judge hears at cop's sentencing hearing

In 2013, Lindsay was involved in another violent attack andprosecutor John Baharustaniwants Court of Queen's Bench Justice Michael Lemato rule the use of force was an assault, which could increase Lindsay's sentence.

The victim ofthat attack, Godfred Addai-Nyamekye, stopped testifying mid-hearing, telling the judge his PTSD was "through the roof."

• Police Act 'loophole' allows another officer to resign in face of disciplinary hearing

On a frigid Decembernight in 2013, with temperaturesnearing -30 C,Addai-Nyamekye was dumped by other officers in the East Village at a time when the neighbourhood was sparselypopulated and largely under construction.

He called 911 several times (it was the only phone number he could dial from a locked cell phone) and eventually, Lindsay showed up.

Addai-Nyamekye believed the officer was there to help him, but instead, Lindsay began to attack himusing punches, knee strikes and a taser.

Video taken from the responding CPS helicopter shows the violence.

After being abandoned by police in a desolate construction site in -28 C weather, Godfred Addai-Nyamekye called 911. After 15 minutes, a different officer, Const. Trevor Lindsay, arrived on the scene, and Addai-Nyamekye was tasered and beaten. Following the incident, Addai-Nyamekye was charged with having assaulted Const. Lindsay, but helicopter footage of the event helped to prove otherwise.

Criminal charges were never laid against Lindsay for his use of force against Addai-Nyamekye, but he did face charges under the Alberta Police Act until he quit the service last year ahead of a disciplinary hearing.

A two-week sentencing hearing was supposed to wrap in early May, but was derailed whenAddai-Nyamekye said he couldn'tcontinue his testimony.

On May 25, 2015, Daniel Haworth was arrested by Lindsay, suspected of breaking into his ex-girlfriend's home and stealing coins from her collection.

Haworth was taken to the arrest processing unit (APU) where surveillance video captured what then took place in the parking lot.

There, video shows Lindsay pulled Haworth, who was handcuffed, out of the police cruiser and pressed himface-firstinto the car.
