A Dallas police officer was fired Tuesday after an investigation found he used unnecessary force during an arrest, didn't follow department procedures, used profanities and turned off his recording equipment.

Joshua Forner, 35, was accused of using inappropriate force and turning off his camera before another officer arrived for backup on Aug. 8, 2015. The internal investigation found Forner entered false information on a police report six days after the arrest. Then, in August 2016, the 10-year veteran of the force gave inconsistent statements during the department's internal investigation, according to Dallas police officials.

Dallas officers must use the video cameras in their patrol cars during "questioning, arresting, detaining, frisking, or searching a person or vehicle," according to the Dallas Police Department's policies.

The officer was suspended for 10 days in 2008 for lying about a traffic accident that year. Forner initially told an accident investigator that he wasn't in his patrol car when it was hit. He later admitted that he accidentally hit a pole at an east Oak Cliff apartment complex.

Forner worked in the South Central Patrol Division. Interim Dallas Police Chief David Pughes made the decision to fire him. Fired officers are allowed to appeal their termination.
