(CNN) Two police officers in an Atlanta suburb who joked about using a coin-flip phone app before one of the officers arrested a woman for reckless driving have been fired, Roswell, Georgia, police said Thursday.

The firings were effective Thursday, according to memos written to the officers by Police Chief Rusty Grant.

Grant cited policies that state officers should serve the public in a "kind, considerate, and patient manner" and should refrain from conduct that destroys public respect for the officer or the department.

Courtney Brown and Kristee Wilson were involved in a traffic stop on April 7 after Brown pulled over Sarah Webb, who said she was on her way to work. Body camera videos from the incident were released earlier this month.

CNN has reached out to Wilson but did not receive a reply. CNN has been unsuccessful in efforts to reach Brown.
