The sister of a man missing for three weeks has said everyone is “desperate to know where he is”.

Joe Warren, who is from Hackney, was last seen at around 9.30am on July 25 by Marsh Gate Bridge in Hackney Marshes.

Joe’s sister, Rosie, has said that the 46-year-old was “so loved by so many people” as police renewed their appeal for information about his whereabouts.

Police said they continue to focus their attention in the Hackney Marshes and Epping Forest area.

Rosie said: “All of Joe's family and friends are desperate to know where he is. He is so loved by so many people and we all want him to come home.

"I've shared a house in Hackney with my brother Joe for over 10 years so every day not seeing him and not knowing where he is, if he is safe or needs help, is agonising.

"The police have been amazing and continue to do so much trying to find him. So many friends have helped us either putting up appeal posters or sharing Joe's appeal on social media, but sadly we still haven't found him.

"If anyone knows or has seen anything that might help us please contact the police or the charity Missing People.”

Joe is described as 6ft 3ins tall and of slim build, with short brown hair which is thinning on top.

He was last seen wearing a green camouflage jacket, green trousers and black trainers with white soles.

“I am asking for the public to support us in this investigation, and to come forward with any information which could assist in locating him safely.

“This continues to be a difficult time for Joe’s family."

Any witnesses, or those with any information, are asked to call Police on 101 quoting reference 23MIS025447.
