BOSTON (AP) — A Massachusetts man who served a prison sentence for coercing a teenager into prostitution is facing new state charges, including human trafficking along the East Coast.

Ryan Duntin, 31, of Randolph was indicted Tuesday by a statewide grand jury on charges that also included rape, deriving support from prostitution and failing to register as a sex offender, Attorney General Martha Coakley said.

Coakley alleged that Duntin recruited women for prostitution and advertised sex services on websites. He allegedly drove the women to hotels along the Interstate 95 corridor in states including Massachusetts, Rhode Island, Connecticut, New Jersey, Pennsylvania and Maryland, taking the money they earned and threatening them with violence. Coakley alleged that Duntin raped one of the women.

Coakley said her investigation began in July on a referral from Tewksbury police.

Duntin was arrested Sept. 23 in Rhode Island on a probation violation and is being held without bail, pending an Oct. 8 hearing. It wasn't immediately known if he has an attorney. His arraignment on the new charges has not been scheduled.

Suffolk District Attorney Dan Conley in Boston said Duntin pleaded guilty in 2007 to one count of inducing a minor into prostitution and three counts of deriving support from prostitution. He served a three-year sentence and was placed on five years' probation. Conley said the case was among those leading to a state law against human trafficking.
