Councillor Julian Bell, leader of Ealing Council said: “I am appalled that these plaques have been forcibly removed and stolen.
“They commemorate the untimely deaths of two young men in our borough. Blair Peach, a teacher from New Zealand who tragically lost his life in the 1979 Southall riots, and Gurdip Singh Chaggar, an 18-year-old student who was murdered in an unprovoked racist attack in 1976.
“The third plaque acknowledges Misty in Roots, a local reggae band known for their anti-racist stance and support for independence in Zimbabwe. They were at the protest in 1979 and their manager, Clarence Baker, was severely beaten and badly injured during the unrest.
“We will work with the police to identify who has removed them and I urge anyone with information of this theft to report it.”
The plaques were removed on Thursday, 11 June. To report information call 101 and provide the crime reference number 2515276/20.
