BOSTON (AP) -- The former executive director of the Chelsea Housing Authority already serving a three-year prison sentence for under-reporting his salary has pleaded guilty to an additional charge.
Michael McLaughlin pleaded guilty Monday to rigging the inspection process for federally-funded housing units at the authority.
The housing authority provides housing to low-income residents and the elderly.
Prosecutors say McLaughlin, 68, a Dracut native, was tipped off in advance about which apartments would be inspected, allowing him to clean up those units before the inspections. The inspections were supposed to be random.
The scheme helped the Housing Authority win a "high performer" designation from the U.S. Department of Housing and Urban Development.
He is scheduled to be sentenced next month.
McLaughlin pleaded guilty last year to filing false reports to conceal his inflated $360,000 annual salary.
