Police investigating the murder of Manchester teenager Jessie James are pursuing a number of leads, following an appeal to catch his killers.
Police are pursuing various leads
The 15-year-old was shot dead as he cycled through Moss Side in September.
Six months on, a £20,000 reward is being offered for information leading to the killer's arrest and conviction.
Police say they have had a number of calls as a result of the new appeal and reward, but stress they still need to hear from anyone else with information.
Det Supt Shaun Donnellan, leading the inquiry for Greater Manchester Police, said: "I know there are people who know who killed Jessie James.
"Some people have been reluctant to come forward and it's because they fear for themselves or their families.
"I promise I can protect you and your family, I can arrange for you to give evidence behind a screen, to have your voice distorted so that nobody in your community will ever know you gave evidence.
He added: "Your courage could convict a killer. Think about Jessie's family. They too are victims and their suffering is dreadful. Do the right thing."
