INDIANAPOLIS - The University of Indianapolis police chief and his top assistant have been placed on leave amid an internal investigation.

Chief Mick Reddick told RTV6 that university officials called him in last week to say they were placing him on paid leave, questioning his management style and poor morale among officers.

But Reddick said he believes the investigation involves a training seminar for officers that he and his top assistant, Lt. Jeff Hammon, signed off as having taken part in but did not actually attend.

The university issued a statement Thursday confirming that Reddick and Hammon had been placed on leave, but a spokesman declined to comment on any issues regarding training.

"That's exactly the kind of internal issue that needs to stay internal. It's a personnel matter," said university spokesman Scott Hall.

Marion County Sheriff John Layton said Reddick, who is a member of the sheriff's reserve, has also been suspended from his department.

"I do understand he's on administrative leave, and so for the sake of the public and for the office of the sheriff, we're going to have to put him on administrative leave as well until we get to the bottom of what this whole investigation is about," Layton said.

The University of Indianapolis stressed that campus officers will continue with their duties to keep students safe.
