Police in Nottingham have released a description of a youth they are looking for in connection with the murder of a 17-year-old.
The two-minute silence will be held in The Meadows
Nathan Williams was shot dead while cycling along the Bridgeway shopping precinct in the Meadows on Tuesday.
Police are looking for a black teenager, aged about 18, who was wearing a hooded top and rode away from the scene on Nathan's BMX bike.
A two-minute silence and memorial service was held at noon on Friday.
Members of the community gathered to pay their respects and show their commitment to fighting gun crime in the neighbourhood.
After the murder, Supt Paul Cottee said the answer to Nathan's death "lay in the Meadows community". He has made a fresh appeal for witnesses.
Reverend Glyn Jones, of St Saviours Church and who led the memorial service, said the silence was "a pledge by the community to continue to make the Meadows a better place to live".
