One more Chattanooga police officer has been suspended without pay recently after an internal affairs investigation sustained a number of allegations against him, including improper use of force.

Officer Caleb Corbin, who has been with the department for one year, was suspended on Feb. 15 for 150 hours.

In addition to the improper use of force allegation, the investigation also found he did not properly activate his body-worn camera, violated vehicle pursuit policy and filed false reports.

The investigation also sustained a citizen's complaint of unsatisfactory conduct.

Corbin could not be reached for comment Friday evening.

Until internal files are released, it's not clear exactly what Corbin's offenses were. 

In the meantime, department policy sheds some light on a few of the allegations.

For example, Chattanooga police officers are authorized to use "only the minimal amount of force" reasonably necessary to protect themselves or others, make an arrest, or maintain control of an arrested person.

"Under no circumstances shall the force used be greater than necessary to achieve lawful objectives," department policy states.

Additionally, any officer who uses force against a person "must be able to articulate the specific reason(s) for using the force," according to policy.

With vehicle pursuits, policy states officers are only permitted to initiate a pursuit when there is reasonable suspicion that the suspect has committed or is committing a violent felony.

Violent felonies include murder, manslaughter, aggravated assault, armed robbery, rape, aggravated kidnapping, child sexual assaults and aggravated arson. 

"Officers shall not initiate or become involved in pursuits for traffic offenses, misdemeanors, non-forcible felonies or when the suspect flees for an unknown reason," department policy states.

Corbin is the sixth officer known to have been disciplined in 2019
