Robert Duff has not been seen since January 12

The mother of a missing man from Kilburn has issued an emotional appeal urging Londoners to help trace her son.

Helen Duff has made the appeal following several weeks of anxious waiting after her son Robert failed to turn up to his daughter’s birthday party on January 13.

He has not been seen since and the disappearance of the 37-year-old, who lives in Victoria Road, is described as “completely out of character”.

The family of Robert Duff is offering a reward of up to £5,000, for information which leads to his whereabouts.

He is described as white, around 5ft 7” tall and of slim build with short brown hair. He is known to frequent the Holloway, Kentish Town, Islington and Camden areas.

Appealing for help from members of the public across the capital Mrs Duff said: “On behalf of me and my family we are asking anyone who may have any information to help us in finding Robert.

“If you know anything, no matter how small, or know of Roberts’s whereabouts please let us know.

“Also if Robert hears of our appeal and you are in any trouble, we can help you. We would rather you came home. We all love and miss you.”

Mr Duff, who was said to have never missed family events was due to meet his family at 3pm on Sunday, January 13 to celebrate his daughter’s 18th birthday meal.

Mrs Duff added: “Robert never misses family events and was really looking forward to his daughter’s birthday meal. However, he didn’t show up.

“Despite constant efforts to call him, his phone remained off the whole time. By the next day, the family grew more and more concerned as his failure to attend the meal was out of character.

“Even more unusual was the fact that his phone remained off because he is usually in constant contact with either me or his daughters.

“His youngest daughter is finding it particularly hard because she can’t understand why her dad has gone missing.

“She texts his phone every night in the hope that he will reply and it is devastating for her when she gets no reply.”

Detective Inspector Mike West, of Brent Public Protection Group, added: “I fully support the words from Robert’s family, and ask anyone with information on the whereabouts of Robert to call us immediately or speak to Crimestoppers anonymously.

“This is a distressing time for Roberts’s family, so please help them by giving us any information that will take us closer to tracing him.

“I would also appeal to Robert that if you are in any kind of trouble then we can help you, just call your family or the police to let us know you are safe.”
