HACKENSACK -- A 10-year-old girl was sexually assaulted on three separate occasions by a 15-year-old boy, a 40-year-old man and a 54-year-old man, prosecutors said.



The girl had told her mother about the sexual assaults, Bergen County Prosecutor John L. Molinelli said.



Police arrested the 15-year-old Monday. He "forcibly engaged in inappropriate sexual activity" with the girl, an acquaintance, Molinelli said.



Vicente Cunalata, 54, was arrested Tuesday. Police have been unable to locate the third man, 40-year-old Luis Solano.



A warrant has been issued for the arrest of Solano, who lives on Central Avenue in Hackensack, Molinelli said. Anyone who knows where he is should call Hackensack Police at (201) 646-7777.



The 15-year-old was charged with two counts of aggravated sexual assault and one count each of sexual assault by sexual contact and endangering the welfare of a child. He was sent to the Juvenile Detention Center in Teterboro.



Cunalata, a Moonachie resident, was charged with a count each of aggravated sexual assault, sexual assault by sexual contact and endangering the welfare of a child. He was sent to Bergen County Jail in lieu of $300,000 full bail.
