A Boston cop who had his city-issued gun allegedly stolen by two strippers after a night out bar-hopping last week in Rhode Island is not being identified because he is “a victim,” police told the Herald today.

He is listed as the No. 1 victim in a Pawtucket police report showing he frantically called cops there early Saturday to report his black, .40-caliber Glock 22 semi-automatic was gone.

The unnamed officer’s service weapon — owned by the Boston Police Department — was taken while he was with the women when they stopped at a hotel bar and later a strip club before ending the night at a hotel in Pawtucket, R.I., a police report states. The officer had been carrying the weapon earlier in the night before locking it up in his car before heading into the strip club, the report states.

“He has been placed on administrative leave with pay and we have opened an internal affairs investigation,” Boston police spokesman Detective Sgt. John Boyle told the Herald on Thursday night. He declined to identify the officer or comment further.

Pawtucket police Detective Sgt. Christopher Lefort said today the gun was anonymously dropped off at a fire station on Hartford Avenue in Providence. He also said the Boston cop is not being named, adding, “He is a victim. It is standard operating procedure.”

Pawtucket police reported the cop alerted them to the missing gun at 3 a.m. Saturday and the strippers were later caught. Melissa Dacier, 22, of Providence, and Neish Rivera, 25, of Pawtucket, were charged with felony larceny of a firearm and conspiracy, according to the police report.

The officer told police he had locked his service weapon in the glove box of his BMW 328i and, later, asked one of the suspects to grab his charger out of his car while all three were at a Pawtucket hotel after the night out, according to the report. The key to a “cable lock” on the gun had been left in the cup holder of the car, the officer told police.

The off-duty cop told Pawtucket investigators he started the night at Nara Lounge in Providence and then went to the Cadillac Lounge strip club.

Police added the unnamed officer said he broke up a fight between the women and another man at a Pawtucket hotel and that’s when they went to his room.

Dacier and Rivera were arraigned Monday at District Court and were ordered held without bail on a prostitution charge for Rivera — at the Foxy Lady in Providence — and a felony charge of assault with intent to commit felonies for Dacier.

The wild night began when the unidentified Boston cop connected with one of the women via Instagram, a popular social media site.
