A video showing a man on a motorcycle kicking down a pedestrian on a busy road in Nanjing, east China's Jiangsu province, recently went viral.

In the video, a couple was crossing a street with heavy traffic, when a man riding a scooter passed behind the couple at a high speed and suddenly kicked the woman from behind. The woman fell down to the ground. The perpetrator sped away without a word.

According to local police, the perpetrator, a 32-year-old Polish student studying in a Nanjing university, has been detained. The man was punished with administrative detention for three days.

It can be seen from the video that this road's outer lanes were full of parked cars. Only two lanes in the middle were available for traffic. The couple did not use the crosswalk.

A lot of netizens condemned the behavior of the kicking man saying that even the woman didn't use the crosswalk, she should be punished by the police. The man's behavior had put the woman into a very dangerous situation.

A reporter from Beijing Youth Daily contacted the victim, Ms. Xu, who said that the incident happened in the morning after she and her husband dropped their child off at school. The road was full of other parents’ parked cars. After Ms. Xu was kicked down to the ground, her knees and hands were bleeding.
