On Thursday 4 October, the Hong Kong Chief Executive Carrie Lam invoked the Emergency Regulations Ordinance to introduce a ban on wearing face masks.
The ban came just before a long weekend. Monday 7 October was Chung Yeung Festival, a public holiday. From Thursday evening, protesters staged incessant and widespread attacks on MTR stations, Chinese banks, and pro-China businesses, and conducted violent clashes with the police in many parts of the city.
One more protester, this time a 14 year old, was shot — in the leg, by a policeman who was cornered by a large crowd and was nearly set alight
