Mall knife attack suspect venting against society: Beijing police
Beijing police said the man who allegedly randomly attacked people at a busy Beijing shopping mall with a knife was venting his grievances on society and did not know any of the victims.
One person was killed and twelve others injured in the attack at the Beijing Joy City shopping mall on Sunday. The suspect, surnamed Zhu, became depressed after being frustrated at work, had conflicts with his employers several times and was addicted to online games, the Beijing police said on Sina Weibo on Tuesday.
They added that Zhu was not related to any of the victims.
They also said Zhu dropped out after graduating from junior high school and had frequently changed jobs. He rarely communicated with others and had even cut off contact with his family, they said.
Zhu has been unemployed since the end of 2017.
After the attack, Beijing upgraded its security measures to the highest level beginning Sunday, and about 200,000 security guards, including community Party officials and patrol teams, began conducting night patrols. They are focusing on areas including traffic hubs and nighttime entertainment venues.
More than 700,000 security volunteers also began patrolling Beijing streets on Monday after the attack.
The security volunteers, including residents wearing red armbands, will strengthen patrols at traffic hubs and densely-populated areas, including business districts. They will work with police departments to report any suspicious movements and contribute to a peaceful Spring Festival environment, the Beijing Daily reported.
