People said they were arrested against their will.
Police are investigating a possible human trafficking operation after at least 26 people were found locked up in a home in southwest Houston.
Most people told police that they were arrested against their will and locked up in the house for a few days to a week.
Investigators said the victims were picked up in Brownsville, Texas, but originally came from other countries such as Mexico, Honduras, El Salvador and Cuba, the KTRK reported.
The 26 people have since been taken to the Ridgemont Primary School gymnasium, the police said.
Investigators are treating the case as a human smuggler and cooperating with the U.S. Department of Homeland Security, police said on Twitter.
Houston police said potential suspects have been detained and are waiting for immigration officials to begin an investigation, the KTRK reported.
