The Estevan Police Service made a significant arrest last week involving a semi-automatic rifle.

"The Estevan Police Service Drug/Intelligence Unit has laid a firearm trafficking charge on a male involved in a 2016 marijuana trafficking investigation within Estevan," explained Police Chief, Paul Ladouceur. "The ongoing investigation revealed the male unlawfully sold a semi-automatic rifle to an individual."

"During the time of the offence, the male was on a 10 year weapons prohibition order. On February 28, 2018, police members located and seized the firearm that was trafficked in this investigation."

"As a result, David Allen Tierney (37) of Estevan, Saskatchewan has been charged with trafficking a firearm under the Criminal Code and possession of a firearm when prohibited under the Criminal Code."

"Tierney was arrested on February 28, 2018, in Estevan."

He was held in custody and made his first court appearance on March 1, 2018, at the Estevan Provincial Court House. His next court date is set for March 26th, 2018.

Ladouceur goes on to say that the charges are not common but they are concerning, especially because they coincide with a marijuana investigation that was initiated in 2016.

"As a result of that ongoing investigation, officers discovered through various means that he was trafficking in this firearm and wanted to seize that firearm and get it off the streets."

"Kudos to the officers who took this upon themselves to further investigate. It goes to show, and I've said it many times before, it sometimes takes longer than anticipated to get results from some of these investigations but these investigations never just stop, they continue on and eventually lead to arrests and charges."
