A news report says Rio de Janeiro police have detained a 14-year-old suspected of participating in the brutal gang rape of an American student inside a moving public transit van.

Monday's O Globo newspaper said the teen was apprehended in a hiding place in downtown Rio on Sunday.

He is the fourth suspect to be taken into custody in the March 30 attack on the American and her French companion, who were held for six hours, robbed and beaten before being dumped by the roadside. The other three suspects, aged 20-22, include the van's driver.

The report says the teenager was the van's money-taker. It says he has acknowledged robbing the couple and beating the man but denied taking part in the rape.

Multiple calls to the police went unanswered.
