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.

A popular Chinese restaurant chain is offering refunds to more than 4,100 diners after two teens were caught on video urinating into a vat of hotpot broth.

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.
