Hong Kong riot police move in to clear protesters on Castle Peak Road, the main road in Yuen Long, on Saturday (September 21).

Protesters had gathered nearby in Yoho Mall I in Yuen Long to mark two months to the day that suspected triad members attacked protesters and members of the public at Yuen Long MTR station.

Video also shows riot police moving onto a smaller nearby road famous for street food in an attempt to clear protesters, despite the fact no protesters could be seen on the street, according to the filmer and local journalist Dave Coulson.
