CENTRAL FALLS, R.I. -- Three armed men broke into an apartment and raped a woman who is seven months pregnant while her 9-year-old son was home, police said.

The woman, who is in her 20s, was asleep with her son early Saturday morning when three men kicked in the door to her third-floor apartment in Central Falls, police said. She was threatened at gunpoint, and one of the men raped her in a bathroom, police Capt. James Mendonca said.

The boy was in the bedroom during the rape and "might have overheard something," he said. The alleged victim told WLNE-TV that the boy saw "everything."

The men also took a game system and television set from the apartment, but the woman refused to tell police whether any firearms or drugs were stolen, Mendonca said. He said the stolen items have not been recovered.

One suspect was taken into custody, charged and later released, Mendonca said.

Central Falls Police Chief Joseph Moran identified the suspect as Joiseth Osorio, 22, of Central Falls. He was charged with first-degree sexual assault, felony assault with a dangerous weapon, using a dangerous weapon during commission of a violent crime, breaking and entering and possession of a firearm without a license, Moran said.

There was no attorney listed for Osorio in court records, so it's unclear if he has one.

The woman reported the attack to authorities at 3:10 a.m. Saturday, according to Mendonca. She suffered minor scrapes and abrasions and was taken to a hospital, where a rape kit was used to gather evidence.
