YouTube star shot dead after mocking Mexican drug lord

A teen social media star has been brutally shot dead while partying at a nightclub after mockingly telling a notorious Mexican drug lord to perform a sex act on him.

Juan Luis Lagunas Rosales - who goes by the alias 'the Pirate of Culiacán' on his wildly successful YouTube and Instagram profiles - was shot more than a dozen times by members of Jalisco Nueva Generación, Mexico's fastest-growing cartel.

His death came less than month after the 17-year-old was filmed telling Nemesio 'El Mencho' Oseguera Cervantes, the cartel's leader, to "suck my dick".

On Monday night, Rosales had unintentionally shared that he was at a nightclub in western Mexico on Instagram, allowing the cartel to track him down.

A bar employee was also killed in the nightclub shooting, reports say.

The teen was best known for making videos that showed himself drinking excessive amounts of alcohol and cracking jokes. His sudden rise to fame as a 15-year-old saw him feature in music videos alongside a several Mexican artists, which further boosted his profile.

He had more than 1 million followers on Facebook and 300,000 on Instagram at the time of his death.
