Two strippers are accused of stealing a handgun from a Boston police officer while he was “hanging out” with them in his room at the Pawtucket, R.I., Hampton Inn.

Pawtucket police arrested Melissa Dacier, 22, of Providence, and Neish Rivera, 25, of Pawtucket, and recovered the officer’s service weapon on Saturday, hours after he’d reported it stolen.

The Boston officer called police just before 3 a.m., after the two women left him alone at the hotel — and he realized his .40-caliber Glock 22 was also missing.

The officer, whose name was redacted from a police report, said that his evening began with an arrangement to meet “Natalia,” whom he’d met on Instagram, at the hotel bar. Pawtucket police determined that “Natalia” was actually Rivera, who is one of the dancers charged with prostitution at the Foxy Lady club in December.

The Boston officer told Pawtucket patrolman Andrew Torres that he and “Natalia” went to Nara Lounge in Providence and met her friend “Melissa,” and then all three headed to the Cadillac Lounge strip club, according to a police report.

The officer said he’d locked his service weapon into the glove box of his BMW before going into the strip club. The three “spent some time” in the club, and then went back to the Hampton Inn.

The Boston officer said he had to break up a fight between the two women and another man at the hotel who accused the women of stealing something, according to the police report. Once inside his room, the officer said he and the women “hung out,” and then Melissa said she needed a phone charger.

The officer said he gave Melissa his keys to get his charger from his car; she returned after a while and said she needed to “step out to use the phone,” according to a police report. Then, “Natalia” said she had to go find her friend, and she left the hotel, the Boston officer told police.

When “Natalia” didn’t return, the Boston officer said, he went to look for her, checked his car and saw that the glove box was open and his gun was gone.

The Pawtucket police figured out the identities of “Natalia” and “Melissa” and arrested both, charging them with felony larceny of a firearm and conspiracy.

Dacier and Rivera were both arraigned Monday at District Court, where they were both ordered held without bail as violators of previous charges: a prostitution charge for Rivera and a felony charge of assault with intent to commit felonies for Dacier.
