A Forsyth County Sheriff’s Office detective who was fired earlier this month after allegedly being found intoxicated while on duty at a public event, has now been arrested and charged with driving under the influence by local authorities.

Gregory Martin Cannon, 46, an investigator with the sheriff’s office major crimes unit, was taken into custody on one count of DUI on Tuesday, Sept. 24, according to sheriff’s office spokesman Cpl. Doug Rainwater.

“We believe he came to work intoxicated and subsequently he drove a county car to work,” Rainwater said.

Cannon was terminated from the sheriff’s office on Sept. 13, following an internal affairs investigation which reportedly found that he violated the sheriff’s office’s policy which prohibits on duty use of alcohol by employees, according to a press release from Forsyth County Sheriff’s Office.

According the release, the internal affairs investigation began on Sept. 11, when individuals attending a public event reported to their supervisors that Cannon, an on duty investigator, appeared to be intoxicated at the event. Agency commanders were immediately notified of the situation and reportedly confronted Cannon within minutes.

“Based upon the initial investigation [Cannon] was immediately placed on administrative leave and taken for an alcohol test by agency supervisors,” the release states. “The Office of Professional Standards began an investigation of the employee’s conduct and upon a review of their internal affairs findings; the employee was terminated from the agency.”

Cannon had worked for the agency since 2007, Rainwater said.

After being booked into the Forsyth County Jail, Cannon was released on Tuesday afternoon under a $2,770 bond.
