ALEXANDRIA, Minn. (AP) — Police say a Minnesota teenager who had been missing was abducted, physically and sexually assaulted and held against her will for 29 days.

The 15-year-old had been tied up and threatened with weapons. Alexandria police say she escaped Tuesday, swam through a lake and was found running in a field in Grant County.

She has minor injuries. Three men have been arrested and charges are pending.

The Associated Press generally does not name victims of sexual assault and is no longer naming the girl.

She had been missing since Aug. 8. Police say she knew one of her captors and left her Alexandria home with him after he said he needed help. Instead, he took her to his home, tied her up with zip ties and began assaulting her.
