The Epoch Times reported that, at around 1:00 p.m. in the afternoon on February 11, a man used a knife to attack people in the “Joy City” shopping center in Xi Dan district of Beijing. He killed one woman and injured 12 other people. The suspect was arrested on the scene. He was identified as a 35 year old male from Henan Province and allegedly used the knife to attack people to vent his personal anger. Beijing raised the security alert to level 1. Starting at 9:00 p.m. on the same day, 200,000 police were seen patrolling the streets overnight, especially in populated areas such as at public transportation stops, stores open for 24 hours, and businesses open late at night. The next day, over 700,000 people wearing red armbands, a red hat and “Chaoyang resident (indicating a security force consisting of common people)” could be seen patrolling the streets throughout Beijing. People’s online comments following the official media report expressed concerns for public safety and questioned why 200,000 security forces needed to be mobilized to patrol the streets. Other than the official news report on the incident, the rest of the online postings, videos, or news were blocked.
