Police still searching for missing man
Mr Brown, aged 28, was last seen at his home address on The Forge in Lydbrook, Gloucestershire at around 11.30am on Wednesday, January 15.
A full police search of the immediate area, including police dogs and the police helicopter, has been conducted but has produced no trace.
Officers are concerned about his welfare and say he left home with little, if any, money and few personal possessions.
They think Mr Brown, originally from Oaken Grove, Newbury, may have returned to the Newbury area.
Daniel is described as white, around 6ft tall with collar-length dark brown hair and a beard.
He was wearing a lime green beanie hat, black trousers, a black fleece top and boots.
Inspector Rachel Lynch-Warden of Gloucestershire Constabulary said: "It's mystifying and very concerning.
"His phone was switched off and he may only have had a few pounds.
"The family moved to Lydbrook very recently so it is possible he could have travelled to his previous home in Newbury.
"He is also an avid gamer so maybe he met someone through his hobby and set out to see them.
"Whatever has happened we just need everyone in Lydbrook and the surrounding area, and people in Newbury, to remain alert and call us if they see Daniel.
"To Daniel we would say please get in contact. Many people are worried about you and want to know you're safe."
Anyone with information that could help find Mr Brown should call Gloucestershire police on 101, quoting incident number 414 of January 17.
