WATCH: Rookie cop brutally beats handcuffed woman pinned to wall -- as other officers watch

The Jacksonville Sheriff's Department fired a rookie deputy on Thursday after video was released showing him brutally punching a handcuffed woman he had pinned to a wall, reports JAX4.

In the video, 31-year-old Mayra Martinez can be seen being punched repeatedly by Akinyemi Borisade as she was being booked into Duval County Jail on charges of trespassing and resisting arrest.

According to police, Martinez was taken into custody after she became drunk and belligerent after she quit her job at a local bar on the first day. The police report states that she battled with officers when being placed in the police cruiser.

In surveillance video taken at the jail, Borisade can be seen placing a handcuffed Martinez against a wall where she she lashed out with her foot twice, attempting to kick the officer. As three fellow officers and another handcuffed suspect stood by, Borisade is seen repeatedly punching the defenseless woman who fell to the ground after the assault as the officers ignored her.

According to Undersheriff Pat Ivey, jail employees brought the video to their superiors leading to Borisade to be fired with prosecutors filing assault charges against him.

"He could have turned her around and held her in a transporting position that they are trained in back over to the location to wait by the door," Ivey said in a statement. "He could have stood there with her, but there was no need to strike her."
