BUENOS AIRES, Argentina (AP) Gunmen threatened Argentine soccer superstar Lionel Messi in a written message left Thursday when they opened fire at a supermarket owned by his in-laws in Argentina, police said.

Nobody was injured in the early morning attack, and it was unclear why assailants would target Messi or the Unico supermarket in the countrys third-largest city of Rosario, owned by the family of his wife, Antonella Roccuzzo.

The citys mayor, Pablo Javkin, went to the supermarket and lashed out at federal authorities over what he called their failure to curb a surge in drug-related violence in Rosario, located about 190 miles (300 kilometers) northwest of the capital of Buenos Aires.

Police said two men on a motorcycle fired at least a dozen shots into an Unico branch in the early hours, leaving a message on carboard that read, Messi, were waiting for you. Javkin is also a drug trafficker, so he wont take care of you.
