Mark Duggan's family has appealed for calm before a vigil planned to be held in his memory tomorrow, amid anger at a jury's decision that he was lawfully killed by police.
Carole Duggan, whose nephew died after being shot in London in 2011 by armed police who believed he was holding a gun, sparking riots, said she wanted "no more demonstrations, no more violence".
However, pledging to mount a legal fight against Wednesday's inquest verdict that Mr Duggan was lawfully killed despite being unarmed, his aunt said: "We will not give peace to the authorities until we get justice."
She said the "struggle" would continue in the fight for answers.
The Duggan family plans to hold a gathering outside Tottenham police station tomorrow, but there have been concerns it could spark a repeat of the rioting across England 48 hours after he was killed in 2011.
"I very much respect Mark Duggan's aunt for saying they want to pursue their case through the courts rather than on the streets," British Prime Minister David Cameron said.
Mr Duggan's mother, Pamela, wants to overturn a High Court decision which found last summer she did not have an "arguable case" for a judicial review of guidance intended to stop police officers conferring before giving statements.
Her application for permission to take her case to the Court of Appeal is expected to be heard on March 7. (© Independent News Service)
