Shanghai police say two 17-year-olds were placed in "administrative detention" following the incident at a restaurant where diners simmer food at their own tables.

Chinese hotpot giant Haidilao said it would compensate over 4,000 diners who had visited one of its outlets in Shanghai.

Two 17-year-old males have been detained by police in Shanghai, China, for allegedly urinating into a hotpot at a Haidilao restaurant and posting the video online, reports Global Times. The worrying incident dates back to last month.

China's huge hotpot chain Haidilao is offering to compensate a staggering 4,000 diners who dined at one of their Beijing locations. Why? Because of a video that went viral depicting two teenagers urinating in the hotpot broth.
