PLAINFIELD -- A former police officer is appealing the city's decision to fire him last year after he admitted to having sex with several women while on duty, myCentralJersey.com reports.

The Union County Prosecutor's Office discovered Fernando Sanchez's trysts while investigating another police officer who was convicted of coercing a woman into stripping for him while he masturbated in a public parking lot, the report says.

Sanchez was never charged with a crime but received 12 departmental and administrative charges from Plainfield's police department, according to the report. His last day in the department was Sept. 22, 2014, the report says.

He is now appealing his termination to the state Civil Service Commission, the report says.

Correction: A previous version of this story incorrectly stated Sanchez's last day in the police department.
