Thousands of Hong Kong residents held a sometimes scrappy anti-government protest on Wednesday at a suburban subway station that was attacked by a mob last month, angry that nobody has yet been prosecuted for the violence. Some masked protesters clashed with police, spraying fire extinguishers from the inside of Yuen Long station as others smeared the floor with cooking oil, beer and detergent to stop the police advancing. Others threw empty fire extinguishers at police lines.
