It's almost been four years since Bijan Ebrahimi was beaten to death and set alight in Bristol after he was wrongly accused of being a paedophile.
The family of Bijan gathered today to plant a tree in his memory. His sisters, Manisha Moores and Mojgan Khayatian, hope this tree will help keep his name alive as act as a symbol against hate-crime.
But the family have said their grief is being made worse as final investigations into Bijan's death are yet to be published.
The Independent Police Complaints Commission launched an inquiry into Avon & Somerset Police's contact with Mr Ebrahimi in the years before his death. Bristol City Council's investigation has concluded but won't be released until the IPCC has reported back.
Avon and Somerset's Chief Constable Andy Marsh today publicly apologised.
Iranian Bijan Ebrahimi was a disabled man who lived alone. He was murdered by his neighbour on his doorstep in July 2013. He was confronted by an angry mob when his neighbour, Lee James, wrongly accused him of spying on his children. When Mr Ebrahimi told police he feared for his life it was he who police arrested.
Two days after police released him, Lee James punched and kicked him to death. He then dragged his body down the street, where another man set him alight.
Last year, PC Kevin Duffy, 52, and PCSO Andrew Passmore, 56, were found guilty of misconduct in a public office in connection with the death of Ebrahimi.
