A Chinese father has been detained on a charge of assault after allegedly slapping a boy from his son’s kindergarten and breaking the leg of the boy’s grandfather.
Police in Nanjing, eastern China, said the 33-year-old father, surnamed Lu, went to the other boy’s home on Saturday to ask for an apology after learning the boy had allegedly hit his son at kindergarten earlier that day.
When Lu arrived, he slapped the boy so hard he flew out of the plastic chair he was sitting on and onto the floor, video of the incident shows.
The boy’s 64-year-old grandfather, surnamed Zu, then rushed to defend his grandson brandishing the plastic chair and a wooden chair with which he was allegedly trying to hit Lu.

Police said Lu is accused of then pushing Zu to the floor, leaving him with a broken leg.
