Police in Whitecourt said a suspicious vehicle complaint led to the arrest of a man convicted in the shooting deaths of four RCMP officers in Mayerthorpe in 2005.
Whitecourt RCMP said Dennis Cheeseman was arrested Friday, and charged with possession of a controlled substance.
Late Friday evening, RCMP said the arrest stemmed from a suspicious vehicle complaint from the public.
RCMP told CTV News Cheeseman remained in custody, and the Parole Board of Canada had been notified of the new charges.
He was released from prison in November, 2013, after serving two-thirds of his sentence for manslaughter.
When he was released, it was on conditions that he abstains from drugs and alcohol, and to not associate with criminals until his sentence expires. That was set for April 13, 2016.
Cheeseman, and his brother-in-law Shawn Hennessey, pleaded guilty to manslaughter for giving James Roszko a rifle and a ride to a farm near Mayerthorpe, where the four officers were gunned down.
