A charity set up following the murder of Lee teenager Jimmy Mizen took part in a 'drive for peace' by visiting every school in the area.
Travelling in the Release the Peace Car and Millwall’s double decker bus, organisers of the project visited 72 primary schools and reached out to more than 20,000 schoolchildren across south east London.
Organised by The Jimmy Mizen Foundation along with the Young Mayor of Lewisham and his team, the campaign ended with youngsters forming a giant 'hand of peace' on a playing field at Catford's St Dunstan’s College.
Jimmy's dad Barry Mizen said: "This has been a great two weeks, and a great way to end the academic year.
"We all have a personal responsibility – this has given young people in Lewisham an opportunity to make their own commitment to their community. Jimmy’s legacy is not one of anger, vengeance or fear, but one of hope and peace."
Pupils from every school have added handprints to a cloth, designed to spread a positive message in a borough once dubbed the country's least peaceful place.
The foundation's director of schools Simon Jones said: "The Drive for Peace has had such a warm welcome from every school, each one unique - a line of 700 cheering children, pupils holding giant hands with messages of peace, even a whole school choir singing "The Dawn of Peace" written by their head teacher.
"It’s been overwhelming and humbling. Lewisham is the borough of peace."
Lewisham police's acting borough commander Detective Superintendent Neil Evans said: "This fantastic process has helped 20,000 young people commit to making our borough safer now and in the future. Something which we are all fully supportive of."
