Man detained after teacher injured in knife attack outside Hong Kong school as human-chain protests and class boycotts enter second week
- School representative says teacher at Cognitio College in Kowloon is being treated in hospital
- Thousands of students take part in human chains with few opting to boycott classes in face of school restrictions

A middle-aged man has been arrested in connection with a knife attack on a female teacher outside a Kowloon secondary school as students’ class boycotts and human-chain protests entered their second week.
Thousands of pupils formed human chains outside schools on Monday morning as they continued to push the government to meet their five demands despite last week’s pledge to withdraw the extradition bill.
At the human chain outside Cognitio College in Kowloon, a man injured a teacher who was trying to protect students, according to a representative of the school.
A video circulating online showed an agitated, shirtless man in blue shorts, waving a box-cutter at people dressed in black, with some onlookers trying to calm him.
A police spokesman said they got a call at about 9am about the attack. The force said the teacher, 33, suffered hand injuries and was taken to Queen Elizabeth Hospital. The man had left before officers arrived.
At about 8pm, police arrested a 65-year-old man in a flat in nearby Kai Ching Estate for wounding. He was detained.
