The nephew of a kidnapped pregnant teen was arrested in San Jose for allegedly helping the girl's ex-boyfriend abduct her, according to the Fresno County Sheriff's Department.

Ester Nieves, 17, and her estranged boyfriend, Juan Carlos Martinez, 18, were still missing Thursday.

Nieves was eight-months pregnant when Martinez and the 15-year-old nephew allegedly forced the girl out of her parents' Reedley home Tuesday night, deputies said.

The nephew was arrested Wednesday night on suspicion of kidnapping and burglary and was being questioned by detectives. His name was not released because of his age.
