Two Lawrence Police Department employees have been suspended pending an investigation of alleged inappropriate conduct, Police Chief Tarik Khatib said Monday evening.

Khatib said he could not disclose the nature of the allegations because it was a personnel matter.

“We conduct personnel investigations all the time,” he said. “When we do, sometimes — depending on what the allegations are — we put people on suspension.”

Khatib did not specify whether the employees were commissioned officers or civilian employees. He said the employees had not been arrested on any criminal charges.
