The 38-year-old Hollywood producer cannot leave Mexico until police conclude their investigation, Quintana Roo state investigator Veronica Acacio said.
Police detained Bruce Beresford-Redman as a suspect Thursday after finding his wife's body in a sewer at Cancun's Moon Palace resort, where the family was on vacation.
Her body had scratches on the neck, signs of asphyxiation and a heavy blow to the right temple, said Francisco Alor, the attorney general for Quintana Roo state, where Cancun is located.
Her husband had scratches on his face and arms, he said, and several guests heard an argument in the couple's room Monday night.
"He's the initial focus of the investigation based on their alleged turbulent relationship," Alor said by phone from the state capital of Chetumal.
