A man has been detained for intentional injury in Beijing, local police said Tuesday.

Ding Xiaoping, 46, allegedly attacked a greengrocer with a stool in a brawl on Sept. 17 in Haidian District after the car that carried him smashed the lotus roots of the vendor surnamed Zhang, when it was passing a roadside market of Nanying village near Fragrant Hill.

Ding hit Zhang on the head with the stool he got from a nearby booth despite his companions' dissuasion, according to police officials.

Zhang received 13 stitches when doctors sutured his head injury.

Ding was detained on Sunday for the suspected crime of intentional injury, police said.

Ding offers training classes in Beijing. Some of his students went to the public security bureau of Haidian District Saturday evening to inquire about his case.
