Surprised ... Yes and No.

A Mexican federal official says the police chief of the border city of Reynosa has been arrested for allegedly protecting members of the Gulf drug cartel.

The official says Chief Juan Muniz will be flown to Mexico City on Thursday to be questioned by organized crime investigators.

Muniz has been arrested by federal agents in Reynosa, across from McAllen, Texas, according to the official, who spoke on condition of anonymity because he is not authorized to discuss the case.

Reynosa city officials have issued a news release saying Muniz was arrested Thursday afternoon. Muniz could not be immediately reach for comment and it was unclear if he had a lawyer.

The Gulf cartel is based in Tamaulipas state, where Reynosa is located.
