CIUDAD VICTORIA, Mexico – An American citizen kidnapped in Texas has been rescued by police in the Mexican border city of Reynosa, located across the Rio Grande from McAllen, Texas, but no arrests were made, police said.

Raul Alvarado, a car salesman from Hidalgo, Texas, was being held for a ransom of $100,000, Tamaulipas state police chief Amarante Miranda said.

The 36-year-old American was rescued on Friday, thanks to an anonymous caller who told police that some suspicious people were apparently holding a man against his will at a house in Reynosa’s Longoria neighborhood, Miranda said.

Officers found Alvarado, who had been handcuffed and had his head covered, at the house, the police chief said, adding that the hostage appeared to have been beaten.

Alvarado told police he was abducted on Nov. 23 in McAllen and taken across the border to Reynosa, which is in Tamaulipas, a state in northeastern Mexico.

Alvarado said he received a call on that date from a friend and the man’s cousin, who asked him to meet them at a place in McAllen, but three other people were waiting for him when he arrived.

The three men forced him into a vehicle at gunpoint and drove away, Alvarado said.

Alvarado paid the kidnappers $30,000, gave them a late-model vehicle and handed them the keys to a 2001 Audi in exchange for his freedom, Miranda said.

Alvarado was taken to the Reynosa-Hidalgo international bridge after giving a statement to police and returned to the United States, the police chief said.
