A car bomb has exploded on an interstate in the central state of Hidalgo, Mexico, fatally wounding a police investigator and injuring three others

Acting on an anonymous tip, state police investigators in the city of Tula went to inspect a suspicious vehicle abandoned on the road. The car exploded as the four officers were searching the car. Mexico's attorney general's office, the PGR, has opened a preliminary investigation into the incident, according to a statement by spokeswoman Yazmin Morales. In July 2010, federal police in the northern border city of Ciudad Juarez reported that a man dressed in a municipal police uniform and left for dead was used as bait by assailants to lure authorities to a car bomb that left four people dead. In August 2010, at least two car bombs exploded near the television studios of Televisa in Ciudad Victoria, the capital of Tamaulipas state in northeastern Mexico.
