The fiftieth anniversary of a peaceful protest in Notting Hill that ended in a violent clash, arrests, a trial and exoneration.Trinidadian community activist Frank Crichlow opened The Mangrove restaurant in Notting Hill at the end of the 1960s. It became a focus for the local Black community, and drew visitors from further afield as well. In August 1970, a series of unwarranted police raids prompted a decision by the local community to hold a peaceful protest against the ongoing harassment. On the 9th August 1970, the demonstration began. It had far-reaching consequences.
