MEXICO CITY –  Mexican authorities say they rescued eight Salvadoran migrant youths who had been kidnapped by an equally youthful gang in northern Mexico.

Mexico’s top anti-kidnapping prosecutor says police found a total of 19 immigrants being held at a house in the northern border state of Tamaulipas. All were lying on the floor with their hands and feet bound, including the eight under-age migrants.

Police detained six alleged kidnappers, three under 18, two aged 18 and another aged 22.

At a news conference Friday, prosecutor Renato Sales did not give the exact ages of the minor victims or suspects found in the northern city of Altamira.

In another raid on Wednesday, police rescued two minors and five adult migrants from Honduras who had been kidnapped in the border city of Reynosa.
