Authorities are searching for six federal inmates who escaped a South Texas jail by overpowering a guard and cutting through at least four fences.
Hidalgo County Sheriff Lupe Trevino says the six men escaped at about 11:30 Tuesday night from the East Hidalgo Detention Center.
The privately operated jail is in La Villa, about 20 miles north of the Mexican border.
Trevino says the men are considered "very dangerous and armed."
The Sheriff's Office was leading a search involving more than 60 local and federal officers.
Helicopters and bloodhounds are being used in the search.
Trevino says one of the fugitives is an American being held on drug charges. He says the five others are Mexican nationals thought to be members of a criminal gang known as "Raza Unida."
