A murder probe has been launched after a man wanted in connection with a spate of armed robberies went missing two weeks ago.
Met Police officers have established a crime scene in South Norwood Park, South London, after uncovering a "number of suspicious items".
They believe Jamie Gilbey, 20, last seen on January 27 at his Crystal Palace home, has "come to harm".
Officers had been searching for the 20-year-old in connection with a number of armed robberies, MyLondon reports.
His "distraught" family are aware cops suspect murder, and are now being supported by specialist officers.
Police have stressed the need to get his family answers as soon as possible.
Investigators say they will not be divulging any further information.
They are yet to make any arrests as they continue to comb the park and a local street for further evidence.
Currently, a cordon is in place around a playground.
Detective Inspector Melanie Pressley, Specialist Crime, said: “We fully recognise this news and the police presence in the park will cause considerable concern to local people, however, I want to say that we do not believe there to be any wider risk to members of the community.
"This is a fast-moving and complex investigation, and we're following a number of positive leads as we work to establish what has happened to Jamie.
"Anyone who has information that could help us piece together a picture of Jamie's life and who he had been interacting with should call us immediately.
"Jamie's family are distraught and it is imperative we give them the answers to the questions that they are now asking."
Chief Superintendent Dave Stringer, responsible for local policing in Croydon, Sutton and Bromley, said: “My officers remain on scene and providing a visible presence in the area for some days to come. I urge any members of the public who have any concerns, or information that could help us bring Jamie’s family justice, to approach those officers and speak to them.”
