A video has emerged from China of a karaoke bar waiter being attacked by a group of customers after he knocked a toddler over.

The CCTV footage, captured last week in a karaoke bar in Jiujiang, Jiaxi Province, shows the waiter being stopped and then beaten, reportedly by as many as 20 customers.

According to local media, police arrested three suspects but are still searching for others involved in the attack.
