Teenage boys face rape charges

Three 17-year-old boys have been charged with the rape of an under-age girl at a home in NSW's Blue Mountains.

Police allege a 15-year-old girl was sexually assaulted by the boys at a home in Springwood on August 15 after she attended a party at Faulconbridge.

Three boys arrested in the Blue Mountains on Thursday have been charged with aggravated sexual assault and sexual intercourse with a child aged between 14 and 16 and have been refused bail to appear at the children's court on Friday.
