The vice squad that arrested adult film actress Stormy Daniels at a Columbus strip club in July is now under federal investigation.

Columbus Police Chief Kim Jacobs on Thursday announced the FBI's Public Corruption Task Force is probing the agency's vice section for criminal activity following recent "high profile incidents" that have brought forward a "variety of allegations" against the unit.

The move comes after Jacobs announced in early September all normal operations of the unit had been suspended following Daniels' arrest at a strip club and a high-profile August officer-involved shooting. That pause remains in effect, the release said.

Daniels, whose real name is Stephanie Clifford, initially was arrested for violating the state's no-touch policy at a Columbus strip club, but charges were later dropped.

A member of the vice unit also involved in an officer-involved shooting. On Aug. 23, Officer Andrew Mitchell, who was working undercover, fatally shot Donna Castleberry, 23, after she had stabbed him, according to the Columbus Dispatch.

Mitchell, a 30-year-veteran of the division, was relieved of duty Wednesday, according to the Dispatch.

Vice investigates prostitution, drug offenses and other crimes. The unit's approximately 20 members have ceased most investigations as the department gathers numbers, policies and best practices on running the unit.

"The Division will notify the public before regular operations resume," the release said.

In the meantime, the release said those who have knowledge of criminal activity by members of the vice unit are asked to call the FBI tip line at 614-849-1777.
