This is one of the men police are searching for in connection with an attack on a 78-year-old man.
The raider knocked out the front teeth of retired film cameraman Robert Steele and robbed him of cash.
Police released the suspect's picture today and urged anyone recognising him to come forward.
Detectives believe the man may be behind three other attacks on pensioners in their homes.
Two men burst into Mr Steele's house in Freehold Terrace, Hollingdean, Brighton, when he answered a knock at the door.
He said: "They forced me into my bedroom and the bigger of the two punched me in the face, knocking out my two front teeth.
"He hit me on the head with a torch and threatened me. He demanded a fiver and when I got my wallet, he grabbed it and took all my pension money.
"They really were brutes. I would have given them the money. There was no need for violence."
The attack happened on January 15. Minutes after Mr Steele was assaulted, a woman was robbed at her home in Middleton Rise, Coldean.
Two men kicked their way through the front door and threatened her as she sat terrified in her lounge. She handed over cash before the men ransacked her home.
A short while later, another elderly man was overpowered and robbed at his home in Bevendean Crescent, Moulsecoomb, Brighton.
The latest attack happened on Tuesday afternoon when two men ransacked the home of a man and his wife, both aged 89.
The offenders tricked their way into the house in The Crestway, Moulsecoomb, Brighton, and kept the victims in separate rooms while they searched the house.
They stole pension money and savings and pushed the man away when he tried to snatch the cash back.
Witnesses and anyone with information should contact Brighton CID on 0845 6070 999.
