Raleigh, N.C. — The acting chief of the State Capitol Police and a sergeant under his command are the subjects of an investigation into practices by the unit, according to the state Department of Public Safety.

In a news release issued Sunday evening, Kieran Shanahan, secretary of DPS, said, "I have serious concerns about certain practices involving secondary employment."

He placed Antonio Asion, acting chief of the force, and Sgt. Benjamin Franklin on investigatory placement, or paid leave. Major William Gray, will take over as acting chief for the course of the investigation. 

"We will conduct a thorough investigation and take action as deemed appropriate. So as not to compromise this ongoing investigation, nor publicly reveal personnel matters, the department will not provide additional details at this time," Shanahan said.

The State Capitol Police work at state-owned properties and around the capitol complex in downtown Raleigh to provide security to employees and visitors. A separate police force, the General Assembly police, is responsible for security at the legislative building and the legislative office building and provides security for legislative leaders when they travel.
