Gloucester Police Chief Leonard Campanello, who has received national praise for his efforts to help fight opiod addiction, was placed on administrative leave pending the outcome of an investigation, according to the mayor.

Mayor Sefatia Romeo Theken did not elaborate on the reasons for the investigation. She issued the following statement on Tuesday:

"Effective immediately, today September 13, 2016, I have notified Gloucester Police Chief Leonard Campanello that he has been placed on paid administrative leave until further notice and upon completion of an internal investigation. We will have no further comments at this time."

Last year, Campanello pioneered an innovative way to combat the opiate epidemic when he announced that Gloucester Police will not arrest anyone who walks in high or in possession of controlled substances or paraphernalia. The move was made to help individuals toward detox and recovery rather than treating addicts like criminals
