PROVIDENCE — The police are investigating three shootings over the last several days, including an assault on man who visiting an apartment on Althea Street that they say was being used for prostitution.

Florentin Reyes, 37, of 665 Cranston St., was at the apartment with a friend, Abraham Natareno, of the same address, when he was shot in the leg around 7:45 p.m. Saturday.

Natareno told the police he was having sex with a prostitute in a bedroom when he heard an argument in the living room between the person running the establishment and a person he could not identify. He said he heard a gunshot and saw Reyes burst into the room with a bleeding leg.

They ran out of the house and drove back to their apartment on Cranston Street and called the police.

The police found a shell casing and blood on the floor and on a wall of the apartment, as well as two mattresses, pornographic videos, log books, receipts of wire transfers and other items consistent with a prostitution operation.

Reyes was treated at Rhode Island Hospital.

In another incident, the police identified the man who was shot around 2 a.m. Sunday near the Sportsmen’s Inn at 122 Fountain St. as Gilberto Vasquez, 25, of 26 Atlantic Ave. A witness told the police Vasquez was arguing with two men when one shot him with a handgun. The suspects fled. Vasquez was in intensive care at Rhode Island Hospital last night.

Late Thursday night, two young men were shot within 30 minutes of each other in different neighborhoods. At 10:42 p.m., Wilfredo Ramos, 23, was shot in both legs and buttocks near 48 Pekin St. in Smith Hill

At 11:06 p.m., Melvin Brown, 18, was shot in the arm, thigh and lower right leg at 355 Friendship St. in South Providence. Both were at Rhode Island Hospital last night.
