According to media reports, at least one person was killed and several people injured in an attack after a concert in western Mexico.
Unknown people shot a vehicle in front of the bullring in Morelia (about 275 kilometers west of Mexico City) on Friday evening.
A concert by Venezuelan reggaeton musician Danny Ocean had just ended there.
The newspaper "El Sol de Morelia" reported an arrest, citing the police.
The paper spoke of four injuries, a Twitter user of ten.
"I don't understand why this is happening when we came with a message of love!
I don't know what to say, I've never been in a position like this," Danny Ocean wrote on Twitter.
The 32-year-old has many fans in Latin America.
Morelia is the capital of the state of Michoacán, which is repeatedly plagued by drug cartel violence in Mexico.
