Over the past year, some Roswell officers made headlines over a series of blunders.
In November, a Roswell sergeant was demoted to the rank of police officer II after body camera video showed him leaving a 13-year-old boy in a cold patrol car and taunting him in January. He had been placed on paid administrative leave in July, more than six months after the incident.
In April, two officers used a coin toss to decide whether to arrest a woman during a traffic stop. The officers were put on administrative leave pending an internal investigation in July.
And on March 10, officers pulled over an off-duty officer and let him go with a warning after he admitted to speeding and drinking alcohol before driving.
Grant, who served as deputy police chief before becoming chief, had more than 30 years of experience with the GBI before working in Roswell.
