Police say a 3-year-old girl has been beaten to death and her 5-year-old brother assaulted at an apartment in New York City.

They say Jeida Torres was discovered unconscious and unresponsive Saturday afternoon in an apartment in Brooklyn's Bushwick neighborhood.

A Fire Department of New York spokesman says Jeida was rushed to a hospital in cardiac arrest and was pronounced dead there.

Her brother is in stable condition at Wyckoff Heights Medical Center.

Neighbor Keith Best tells the New York Daily News and New York Post that the boy had big bruises on his face and arms. He says the children's mother and grandfather sobbed when they arrived home and found out what had happened.

Police say they have made an arrest, but no charges have yet been filed.
