A Waterloo Regional Police Service officer was sentenced to 60 days of house arrest and one year of probation Friday.

Const. Andrew Robson was found guilty of stealing and possessing marijuana after an undercover sting investigation.

Robson had argued he was under a lot of stress at the time, and ended up abusing drugs and alcohol as a means of coping with post-traumatic stress disorder he developed after dealing with difficult calls.

His lawyer had argued the sting operation, in which another officer posed as a mother giving Robson marijuana she had found on her son in 2007, amounted to entrapment.

Robson kept a small amount of the marijuana turned over to him in the operation.

Defence lawyer Jamie Yoon had requested a conditional discharge, which would have meant no criminal record for Robson, but the judge dismissed that request.

“We’re glad it’s over,” Robson’s father John Robson told CTV.

“The judge was very fair. She’s recognized all the work (Andrew’s) done to get his life back together. He’s a sick man. He’s been suffering for years now. He can finally concentrate on his health.”

Robson apologized for his actions in court, saying once he’s healthy, he wants to help others deal with issues of severe stress, addiction and thoughts of suicide.

Yoon said the defence is now considering its appeal options.

“We’re in the process of figuring out whether or not our client's interested in that,” he said.

Robson still has to face internal discipline, which could mean losing his job, from a police review board.
