From the San Jose Mercury News:

Six members of the Mexican government’s top anti-crime unit have been arrested on suspicion of leaking information to drug traffickers, officials said Wednesday.

An official in the Mexican attorney’s general office said a supervisor and five agents are thought to have passed tips to smugglers in northern Sinaloa state for about three months.

The official, briefing reporters on condition of anonymity, said the men disclosed details about evidence that had been seized during government raids and information about arrestees. He said authorities were looking into possible involvement by other employees of the agency, known as SIEDO by its initials in Spanish.

SIEDO, which investigates drug and arms smuggling as well as kidnapping and terrorism cases, is well-known and generally trusted by U.S. law-enforcement agencies.
