Police detained a man after a social media showed him holding a high-powered rifle and naming the Ultra Music Festival in the caption, according to sources.
City of Miami Police allegedly tracked down the man on Sunday for questioning.
The photo that surfaced on social media shows the subject wearing a dark gray T-shirt, jean shorts and a baseball cap while holding the firearm.
The picture is captioned “Ready for the weekend” and includes the hashtags “#tgif,” “#ultramusicfestival” and #mmw2018,” a reference to Miami Music Week.
After the October 2017 massacre at an outdoor music festival in Las Vegas, security was even tighter at this year’s Ultra. Officials said they are taking any and every form of threat seriously.
Russell was taken into custody just hours after he attended the festival on Sunday. It is unclear whether he will face any charges.
