Mexican mayor probed as drug violence rages

Mexico City - Mexico is investigating Acapulco's mayor for possible links to drug cartels after a series of bloody attacks that have turned the once glamorous Pacific Ocean resort into a gangland battleground.

Federal police chief Genaro Garcia Luna said mayor Felix Salgado is under investigation as part of the government's nationwide drive against the cartels.

Salgado, a leftist, says he has received a string of death threats from drug gangs and professed his innocence in a radio interview on Tuesday. "Let them investigate, they are not going to discover anything at all."

Violence spreading across the country reached a quiet village in the northern state Chihuahua on Tuesday, when police said they uncovered a shallow grave with four bodies inside.
