A Maricopa County Sheriff's Office (MCSO) detention officer was arrested Monday after he was accused of using excessive force.

Authorities say Anthony Nguyen, 48, used his Taser on an inmate without justification on Feb. 19.

According to a press release, the arrest concludes an investigation which began in mid-February when he was put on administrative leave.

“Although I recognize the inherent dangers and challenges that our detention officer’s face every day, I will neither ignore nor excuse actions in violation of the law or in conflict with our oath of office, said Sheriff Paul Penzone in the press release.

MCSO says Nguyen will be fired.
