Detectives have released new CCTV footage and reissued an appeal to help find an elderly man who went missing in north London five days ago.
The 79-year-old was last seen around 13:37pm on CCTV footage at the junction of Finsbury Road and Trinity Road.
He is then believed to have walked in the direction of Wood Green High Road.
Mr Bennett, who at the time of his disappearance was wearing a yellow and black striped shirt and a dark grey jacket, is said to have left his home without any of his personal belongings.
He suffers from dementia and other underlying health conditions and his disappearance is out of character, the Met police said.
Detective Inspector Paul Ridley, from the North Area Public Protection Unit, said: “The more time that goes by without a sighting or a trace of Peter, the more concerned we are becoming. He doesn’t have any of his personal belongings and is badly affected by his dementia. He needs medication which he does not have with him.
“The CCTV footage I’m releasing today shows that Peter was alone, moving slowly and did not appear aware of his surroundings.
“Another person walked past him and may have seen where he went next. I would appeal for that person to come forward.
“We are very worried. Finding Peter is a top priority and we are asking for the public’s help.”
Anyone who sees Mr Bennett has been asked to contact the police immediately as the force believe he is likely to need medical assistance and will be confused and disorientated.
People living in the Finsbury Park area, or elsewhere in Haringey, have also been asked to check their doorbell or dash cam footage for sightings of him.
Anyone with information that could help in the search should call 101 providing the reference 21MIS010616. They can also contact the charity Missing People on 116000.
