A Lambton OPP officer has been charged after an ATV crash back in June in Dawn-Euphemia.

Officials with the Special Investigations Unit (SIU) says Const. Sean Coughlan was working at the Lambton County Petrolia Detachment at the time of the incident.

The SIU investigation revealed that in the evening hours of June 22, 2016, a 24-year-old man was operating an all-terrain vehicle. Sometime later, the man was involved in a motor vehicle collision and sustained serious injuries.

As a result of the SIU investigation, Coughlan is now facing one count of criminal negligence causing bodily harm, one count of obstruct peace officer, two counts of perjury, and two counts of obstruct justice.

Const. Coughlan was arrested today by members of the SIU and subsequently released on an undertaking given to a peace officer.

The officer is required to appear before the Ontario Court of Justice in Sarnia on February 28.

The SIU will make no further comment in consideration of the fair trial interests.

The SIU is an arm’s length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault.

Under the Police Services Act, the Director of the SIU must consider whether an officer has committed a criminal offence in connection with the incident under investigation depending on the evidence, lay a criminal charge against the officer if appropriate or close the file without any charges being laid report the results of any investigations to the Attorney General.
