Paul Conte, 21, is thought to have been wearing a white t-shirt, black jeans, white shoes and had his hair tied in a bun. He is 5ft 10ins and of slim build.
He was last seen at approximately 12.45am on Sunday, 15 August.
He had been to a party in Ferry Road, Barnes, SW13 on the evening of Saturday, 14 August and left in the early hours of Sunday morning at approximately 12.30am
He was captured on CCTV [below] in Galata Road, SW13 at 12.35am and at 12.38am on Parke Road, SW13.
At this time police believe he should have walked through the Barnes area on his way home, and he would have been expected to arrive approximately one hour later.
Paul has not been heard or seen from since, and officers are growing increasingly concerned for his welfare. They are asking people in the area to check their door bell footage to see if there is any sighting of Paul.
Sergeant Amy Everitt, of the Met’s South West Missing Persons Unit, said: “Paul’s disappearance is completely out of character and we are growing increasingly concerned for his welfare.
“Officers are working hard to find him and, we very much want to hear from anyone who has been in contact with him, or may have seen him in the Barnes area at around the time he was last seen. If you live in the Barnes area, especially the roads around Ferry Road, SW13, please check any door bell footage you may have to see if you captured any images of him.
“Please do contact us if you have any information that might help us find him.”
