Prosecutors in New York have indicted a Jamaican-born pastor at a Bronx church for allegedly repeatedly raping a teenage girl in his congregation.

Prosecutors charged that Michael Clare, the 38-year-old married leader of the Harvest Worship Centre in the Wakefield section of the Bronx, repeatedly raped the girl since she was 12 years old.

They said at his indictment on Friday that the girl who is now 15 years old is pregnant.

Authorities said they learned of the alleged abuse in June, when the girl told her parents and police that Clare had sexually preyed on her for years.

Clare was arrested on June 14 on second-degree rape charges, but the grand jury on Friday upped the charges to first-degree rape.

Clare, who is also the principal of Harvest Prep, a school run out of the church, began preaching when he was 11, and became a pastor at 26, according to court documents.

He is being held on US$50,000 bond and faces up to 25 years in state prison if convicted of first-degree rape.
