According to the police report, the girl was visiting family in Fairfield from out of the country and met Bridgeport resident Hilario Perez-Canalizo, 32, at a gym in Trumbull a week ago.
Her family notified police Thursday night that she was missing, police said. She and Perez-Canalizo were later found at Owen Fish Park, police said.
Police said they interviewed Perez-Canalizo and the 15-year-old and determined that an assault had taken place at Perez-Canalizo's Bridgeport house.
Perez-Canalizo was taken into custody and processed at police headquarters. He was charged with second-degree sexual assault and two counts of risk of injury to a minor and was held on $100,000 bond.
After he was charged, the U.S. Department of Homeland Security contacted police to request a phone interview with Perez-Canalizo. Police Sgt. Sue Lussier said Perez-Canalizo was still being held for an unknown reason for Homeland Security.
