Methuen’s police chief is on leave after a scathing report from Massachusetts officials investigating his salary and those of other high-ranking officers.

Mayor Neil Perry said Friday that Chief Joseph Solomon and Capt. Greg Gallant have been placed on paid administrative leave.

The report from Inspector General Glenn Cunha, “Leadership Failures in Methuen Police Contracts,” found that former Mayor Stephen Zanni and the city council “likely violated state laws” and did not comply with Methuen’s rules when Solomon’s contract was negotiated.
