Evo contacts FBI, Twitch following threats of 'mass shooting'

The tournament director for the Evolution Championship Series reported a potential mass shooting threat to the FBI on Saturday following a Twitch message suggesting an attack would occur at the Aug. 3-5 event at Mandalay Bay in Las Vegas.

Joey Cuellar, the tournament director, tweeted Saturday that he was aware of the threat.

Cuellar did not immediately respond to a request for comment. While he did not identify the specific threat, a Twitch user posted "Mass shooting @ EVO18 see you there" during a stream shortly before Cuellar's post on Twitter.

Safety at Evo has been a source of discussion for some time now, with a criticism being the lack of separation between the fans and the players on stage during the event; these lead to questions of match integrity and safety.

In 2016 on Championship Sunday during the Ultimate Marvel vs. Capcom 3 awards ceremony, a topless fan ran onto the stage in the Mandalay Bay to challenge the newly crowned champion, Chris "NYChrisG" Gonzalez. In 2017, there was confusion during the Super Smash Bros. Melee tournament on Saturday with coaches jumping to the stage freely during a match between Juan "Hungrybox" Debiedma and Zachary "SFAT" Cordoni.

After Evo 2017, Cuellar announced rules updates, which included "no coaching during any 'Top 8'" and "Any unauthorized player trespassing on any of the Evo stages including in the arena, may be ejected at the tournament organizers discretion."

Just over five months ago, Stephen Paddock shot and killed 58 people from a suite at the Mandalay Bay during a live concert across the street. Hundreds more were injured in the attack.
