ALLERTON, the Bronx (PIX11) – Two foster kids were beaten and abused while they were held captive in a Bronx apartment for months, police sources said.

Police discovered the two siblings – ages 13 and 14 – in an apartment at NYCHA’s Eastchester Gardens on Tuesday after authorities received a 911 call about a domestic disturbance, according to police sources.

Police found the two teens, who were “very skinny” and malnourished, and took them to a hospital for treatment, sources said. Doctors discovered they also had bruises about their body.

The teens – who are brother and sister – told police they had been beaten with wooden sticks, bats and brooms. They had been handcuffed and tied up with electrical cords and hadn’t been allowed to leave the apartment in months, according to police sources.

Police arrested Michael Ramos at the apartment. Police learned that the siblings were foster children who had been in the care of Ramos’ mother until her death in December, sources said. After she died, Ramos allegedly kept the teens in the apartment and abused them for months.

Ramos was also found in possession of a “defaced” firearm, sources said. He was charged with acting in a manner injurious to a child, assault and criminal possession of a weapon.

PIX11 News reached out to the New York City Administration for Children’s Services (ACS) for comment, but a spokesperson said the agency is prohibited by state law from sharing information about specific cases.

However, in the instances when a foster parent dies, ACS does assess whether someone known to the foster child would make for a safe home. A court would then determine whether to grant guardianship of the child to that person, the ACS spokesperson said.
