These are the kinds of stories that could happen to anybody.

Police subdued a knife-wielding man on Gongye Road in Shenzhen’s Longong District after he attacked a street cleaner with a knife, according to Southern Metropolis Daily.  The attack was apparently completely unprovoked.

A plain-clothes police officer had to first tackle the man and take the knife off him before other officers assisted at around 3:30 p.m. You can watch the scene unfold here.

The victim was a 47 year-old woman named Zou Yinfang, who has worked for Fengcai Cleaning Company for over three years.  She was responsible for that area of Gongye Road.

Her boss, surnamed Li, watched the attack but claimed to have been caught unaware as the attacker was concealing the knife under his clothes. After Zou was attacked, Li rushed to the nearby Longquan Hotel to get a security guard.

Zou’s screams could be heard from nearby buildings and when people rushed to their doors they saw the cleaner covered in her own blood, but the attacker had already left.

After ripping his shirt off, the attacker had rushed some 500 meters north toward Renmin Road by the time police got to him.

During a 10-minute stand-off in which police tried to talk the man into putting his knife down, the man exclaimed that he was from Hunan and he was afraid because people were chasing him and trying to kill him.

Eventually, a plain-clothed officer tackled him from behind and others gathered to subdue him.

The man’s name is Song Quanzhong and he is 29. He has been detained for questioning.

Zou, a 49 year-old woman from Sichuan, received severe injuries to her left arm. She is recovering in Longhua People’s Hospital and is in a stable condition.
