COLBERT, Okla. (KTEN)—The Oklahoma State Bureau of Investigation is investigating certain members of the Colbert Police Department.

According to an OSBI spokesperson, the Bryan County District Attorney's office requested that OSBI look into possible "use of force" by multiple officers.

Both the city of Colbert and the Bryan County DA declined to comment on the matter. The investigation is still in its early stages.

In July, the Colbert City Council terminated police Chief David Petersen for undisclosed reasons.
