Crowds started gathering at around 8 pm, and violence broke out among the protesters in Kowloon about two hours later. On the busy thoroughfare Nathan Road, mobs threw stones at buses and set vehicles on fire. The Yau Ma Tei Police Station was also attacked by a crowd of over 300 people. Riot police fired tear gas in response, but people continued to gather in Nathan Road, with the mob almost doubling in size once Hong Kong's cinemas closed at midnight.
