“A graffiti message found Sunday night in Juárez warned U.S. law enforcement that another car bombing will occur if they do not arrest corrupt federal police agents.

The unsigned message told the FBI and the U.S. Drug Enforcement Administration to investigate authorities that support the Sinaloa drug cartel.

Otherwise, there will be another car bomb placed in Juárez to kill federal police, the threat stated.

“If in 15 days, there is no response with detention of corrupt federales, we will put a car with 100 kilos of C4,” the message read.”
