Christian Theriault, a civilian, has beencharged with aggravated assault, assault with a weapon, and public mischief the same offences faced by Const. Michael Theriault, whowas charged Tuesdayby Ontario's Special Investigations Unit (SIU).

This is the first time the SIU has charged a civilian, the police watchdog confirmed Friday.

"The allegation in this case is that Const. Michael Theriault and Christian Theriault acted together and were parties to the same assault upon the 19-year-old man on December 28, 2016," SIU director Tony Loparco said in a news release.

Michael and Christian Theriault are brothers, according to Julian Falconer, lawyer forDafonteMiller, the 19-year-old who suffered serious injuries following a Dec. 28 incident.

According to the SIU, the twowere "involved in an interaction" with Millerin the area of Thickson Road and William Stephenson Drive in Whitby.

Miller'smother,LeisaLewis, told CBC Toronto that Miller was hit repeatedly with a steel pipe. He is traumatized and awaiting surgery to remove his eye, Lewis said.

Following the December incident, Durham Regional Police arrested Miller. According to his lawyer, he was charged with theft under $5,000, two counts of assault with a weapon, possession of a weapon and possession related to marijuana, but all the charges were withdrawn following a pretrial hearing on May 5.

Miller's lawyer notified the SIU of the incident on April 27.

As protocol dictates, Const. Theriault has been suspended with pay by the Toronto Police Service.
