BARRIO – Gunmen left a threatening message on Thursday for Lionel Messi and opened fire at a supermarket owned by his in-laws in his hometown of Rosario, police said.

Nobody was injured in the early morning attack, and it was unclear why assailants would target the Argentina star or the supermarket, which is owned by the family of his wife, Antonella Roccuzzo.

Police said two men on a motorcycle fired at least a dozen shots into the supermarket in the early hours, and left a message on a piece of cardboard that read, “Messi, we’re waiting for you. [Rosario mayor Pablo] Javkin is also a drug trafficker, so he won’t take care of you.”

Messi, who captained Argentina to victory at last year’s World Cup, has not commented on the incident. Messi plays for Paris Saint-Germain and spends much of his time overseas, though he often visits Rosario where he has a home in the suburb of Funes.

In Rosario, prosecutor Federico Rébola said authorities were reviewing security camera footage and that the investigation was “preliminary.” It was the first time Messi’s in-laws had received this kind of threat, he added.

He said the supermarket was in a section of Rosario that has seen frequent crimes, and that he has raised the issue in recent meetings with federal and provincial law enforcement officials, but no action has been taken.
