Mexican police have discovered an air-conditioned drug-smuggling tunnel

Mexican police have discovered an air-conditioned drug-smuggling tunnel less than 60m from the US border in north-western Mexico, state police said yesterday.
The director of police in Baja California state, Juan Miguel Guillen, said the 140m-long tunnel, 1.3m wide and 5m below ground, contained an electric rail for container transport, ventilation, lights and air conditioning.State officers arrested eight suspects after discovering the tunnel under a house during a patrol in Mexicali, across the border from Calexico in the US, Mr Guillen said. ''The detainees confessed that they were looking after the building where a drug tunnel was being built.'' Agents from the US Drug Enforcement Administration were excavating on their side of the the border to find the tunnel's exit point, he added.Most of the cocaine and marijuana that reaches the United States is trafficked through Mexico, and much of the country's extensive drug trade is controlled by cartels based in border areas.
