A police sergeant in Florida has been demoted to desk work after he was seen on video grabbing a fellow officer by her throat. 

Authorities in Sunrise, Florida shared body camera footage of an incident that took place November 19. 

Everyone in the video had their face blurred except for Sergeant Christopher Pullease, 46, a 21-year veteran of the force. 

Sunrise police were detaining a suspect who was 'verbally and physically resistive' when Pullease came on the scene and got aggressive, Chief Anthony Rosa said in a statement. 

Pullease then got into a verbal altercation with the suspect, who was already sitting inside a police car.

Body camera footage shows Pullease ducking his head inside the car to talk to the suspect while holding a can of pepper spray.   

Rosa said that Pullease was 'inappropriate and unprofessional' in the situation and added that he 'unnecessarily elevated the demeanor of the suspect.' 

A fellow officer - who has not been identified but has been on the force two and a half years - ran toward Pullease and pulled him by the back of his duty belt.  

Video shows Pullease turn around while backpedaling as he was pulled, then momentarily putting his hand at the other officer's throat and pushing her backward until she hits a nearby police car. Pullease then walks away.
