The investigation into a man missing from Barking and Dagenham continues, led by the Met’s East Area Command Unit.
Dennis Farnall, 62, was reported missing from his home address in Stanley Avenue, Barking on December 21.
He was last seen on December 20 in the Thames View area of Barking. He was wearing a black coat, dark trousers and dark shoes.
Mr Farnall is known to frequent Farr Avenue and Bastable Avenue in the Thames View area of Barking. His family and police remain very concerned for his welfare and continue to appeal for anyone who has any information to make contact.
Owing to the length of time that he has been missing, he is considered a high-risk missing person, and officers are investigating potentially suspicious circumstances to establish whether he has come to any harm.
As part of the investigation, on December 24 officers arrested a 53-year-old man , a 24-year-old man and a 47-year-old woman on suspicion of robbery and kidnap. A 20-year-old woman was also arrested.
All four have been released under investigation.
A number of crime scenes in Barking have been established and searched as part of the investigation.
Police are aware of speculation and can confirm that a body has not been recovered from the area.
