Soldiers rescued seven kidnap victims who were being driven in a van through the streets of Monterrey, north Mexico.
In the vehicle, the authorities also found the body of a man. The freed prisoners told the authorities he had been beaten to death by the captives after asking for water.
The army spotted the vehicle after receiving an anonymous tip about armed men in the area, but intercepted it only after a high speed chase through the city streets.
Two of the suspects managed to escape, while one was captured.
Also in Nuevo Leon, the state security spokesman confirmed that 17 policemen from the municipality of Pesqueria have been detained on suspicion of taking part in a kidnapping scheme. They have been in detention since June 9 on suspicion of abducting 20 construction workers in collaboration with organized criminal groups.
