Rio Grande Valley law enforcement officials told Action 4 News that they have received threats from drug cartels saying, 'They will be sorry.'
Zapata County Sheriff Sigifredo Gonzalez said his office received that very threat.
He said, despite the call, his department will continue to do their job and that is protecting the citizens of Zapata County.
Sheriff Gonzalez also said his deputies are on high alert and are told to be extra careful when out patrolling.
"We've received information that there could be mass exodus of cartel members coming here," said Gonzalez. "We're on the lookout and not putting our hands down we're on high alert."
Gonzalez said more needs to be done to protect the border.
He said Mexico need to re-evaluate what is happening on their side of the border -because it is out of control and they need help.
