About 300 inmates have been transferred out of a prison in the Gulf coast state of Veracruz to make room for a film that Mel Gibson reportedly plans to make there.
Ignacio Allende prison director Gerardo Duran says the inmates were being bused to at least four other jails.
About 1,200 prisoners remain at the facility in the city of Veracruz.
About 60 inmates' relatives protested Saturday's transfer, saying they will have to travel farther to pay visits. They scuffled briefly with police.
Veracruz Gov. Fidel Herrera has said that part of the prison would be emptied for a Gibson film.
Gibson representatives have not responded to inquiries.
