The man who poured water on Baidu’s CEO at a major conference has been detained by police, Beijing authorities said on Thursday.

Baidu has strongly condemned the man who doused tech mogul Robin Li’s head during the company’s annual artificial intelligence conference in Beijing, saying in a statement that the man's “malicious” action would cause “public anxiety.”

The event was widely covered by Chinese media. A Weibo user “Zhinanshangshu” is suspected to be the man who embarrassed Li in front of a 7,000-strong audience. The user had been uploading photos to Weibo detailing his plans, and had posted the caption “What will happen if I pour water over your boss’ head?” under a photo of the conference venue shortly before the incident.

Baidu didn’t confirm if that user and the man on stage were the same person, but said the live-blogged incident was shameful and would “cause anxiety” for future attendees of public events.

“If our society tolerated extreme behavior like this, then similar practices could be repeated in future conferences and events, and everyone exposed at public events could be potential targets! People definitely don’t want to see this,” Baidu said.

Baidu said the man had been taken away by police for investigation. Beijing police said on Thursday that the man would be detained for five days.
