The headquarters of streaming platform Twitch are empty today, as employees were told to work from home following a repeated threat of violence over social media.

“We were made aware of a threat against our San Francisco HQ on Tuesday, and have been working directly with law enforcement as they investigate,” Twitch said in a statement provided to Business Insider, The Verge, and Kotaku. “The safety and security of our employees is our top priority, and we are focused on ensuring this is resolved quickly and safely.”

According to anonymous sources that spoke to The Verge and Kotaku, the threat was for a shooting. Kotaku also spoke with the San Francisco police department, who told them this threat has been made multiple times over the last two days, with the most recent threat happening this morning. According to the Kotaku and The Verge reports, police no longer view the situation as an “active threat” and have left the headquarters after arriving prior to 9 a.m. Pacific this morning.

A representative of Twitch did not immediately return our request for confirmation or comment.
