Nine people have pleaded guilty to violent disorder in connection with a riot on a housing estate triggered by the outcome of a murder trial.
The trouble on Bestwood Estate in Nottingham on 1 July started after jail sentences were handed to three men found guilty of plotting two murders.
John Stirland, 51, and his wife Joan, 55, were executed at their bungalow in Trusthorpe, Lincolnshire, in 2004.
The nine will all be sentenced at Nottingham Crown Court on 3 November.
Matthew New, 23, from Bestwood; a 34-year-old woman who cannot be named for legal reasons; Michael Vickery, 19, of Arnold Road, Bestwood; and Luke Rockley, 19, of Arnold Road, Bestwood admitted a charge of violent disorder.
Three girls, aged 15, 16 and 17, and two teenage boys, who cannot be named for legal reasons, also pleaded guilty.
One of the teenage boys and New were remanded in custody. The others were bailed.
Michael Collins, 26, of Raymede Drive, Bestwood, denied the charge and will face trial on a date to be fixed.
Violence broke out on the estate the day after three men - John Russell, 29, Michael McNee, 21, and a 39-year-old who cannot be named for legal reasons - were jailed for life for conspiring to murder the Stirlands at their seaside home.
The Stirlands were targeted in revenge for a murder carried out in Nottingham by Mrs Stirland's son Michael O'Brien.
Police were attacked with petrol bombs and cars were set on fire during the riot.
