LOUISVILLE, Ky.  (WDRB) -- A 14-year metro police officer resigns before the police chief could fire him in a misconduct case that stretched more than a year.

Chief Steve Conrad told WDRB News that 4th division Ofc. David Graham quit Wednesday afternoon.

His resignation comes 15 months after WDRB News revealed video of Graham smacking a handcuffed John Sanders, during a 2012 arrest in Old Louisville.  At trial, Graham said Sanders lied to his face about a violent robbery.

The officer was convicted of harassment and official misconduct, and was ordered to pay a one dollar fine.

Graham had been on paid administrative duty since the altercation, but was told earlier this month about the chief's plans to fire him.

"An officer striking a handcuffed prisoner who was in no way offering any kind of resistance that is unacceptable and something that our people need to understand and our community should understand that I will not tolerate," Conrad said.

Graham served with LMPD for 14 years.
