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 after two diners urinated into their hotpot broth. A video showing two men urinating into the broth of their hotpot while dining in a private room at a Haidilao restaurant started circulating online late last month.
