Apparently, this occurred in his native home of Rosario, Argentina. The gun was found when Matias refused to show officers at a routine stop the papers for his Audi A5.

Both Matias and the police officers involved walked away with minor injuries due to the resulting clash.

After spending 16 hours in police custody, Matias was eventually released and is now under investigation for alleged illegal weapon possession.
