A group of more than 30 migrants, most of them Chinese citizens, was found inside a U-Haul truck Friday after a report of an alleged abduction, Florida authorities said. 

The discovery began when a security guard for a homeowners association in the Miami suburb of Coral Gables reported seeing an abduction around 9:35 a.m., Coral Gables Police Chief Edward James Hudak Jr. told reporters. 

The guard reported seeing a Toyota and a U-Haul truck involved in the incident and immediately alerted a patrol officer, the chief said. The officer then issued a BOLO, a be on the lookout alert, for the vehicles.

Investigators were looking into whether the woman who was possibly being abducted was trying to escape her alleged smugglers. The Coral Gables Fire Department responded to provide medical care to the migrants, who were “tired” but in good condition, police said. 

“Today’s event is a prime example of why FDLE is supportive of the governor’s proposed special session to tackle illegal immigration immediately,” Florida Department of Law Enforcement Commissioner Mark Glass said. “The actions of law enforcement are an integral part in preventing these smuggling ventures that happen too frequently on our southern border.”

The migrants were handed over to the U.S. Border Patrol, and four others were taken into police custody related to the incident. 

“This started off as a crime,” Hudak said. “The police department responded to that alleged crime by a very alert citizen. By that, I mean I think we’ve saved some lives.”

Authorities patrolling the waters near the city stopped several vessels but have not identified the boat in which the migrants were transported, authorities said.
