Portland, OR, Police Chief Mike Marshman and his executive assistant stems are being investigated over police bureau training, where his lieutenant may have signed the chief in on a log suggesting he had attended, when he had not, sources familiar with the inquiry told the Oregonian .

Marshman declined to say what led to the investigation. He said he would let the process run its course.

He and his executive assistant Lt. Mike Leasure were  placed on paid administrative leave late Friday as the city's Independent Police Review Division investigates  the two.

The recent training was for command staff about the use of the bureau's Employee Information System,  a computer-based system intended to identify at-risk employees who have a high number of complaints, or a pattern of excessive use of force.
