Detectives are continuing to investigate the disappearance of a Kilburn man who went missing almost five years ago.
Robert Duff, 42, (19.07.75), has not been seen or heard from since 12 January 2013 when he failed to attend a family celebration for his daughter's 18th birthday.
Officers remain concerned for his welfare and are appealing to the public for any information about the disappearance of Mr Duff.
Robert's two daughters and family remain distraught and are extremely worried about him.
In a statement Robert's family said: "Robert's disappearance five years ago doesn't get any easier to bear.
"As a family he is constantly in our thoughts. We find it especially difficult when birthdays and special dates come around because he is not here to share them with us.
"This year has been particularly difficult for us as he is about to become a grandfather in March. Not being able to tell him the good news has been very difficult for Robert's eldest daughter. This time of year is always hard to deal with because Robert isn't there to join us.
"Our greatest wish is that someone out there knows what has happened to Robert or knows where he is and passes information to police or anonymously to Missing People."
Robert was last seen on CCTV at 11:12hrs on Saturday 12 January, 2013. He was withdrawing money from a cash machine outside Sainsbury's in Holloway Road.
Detective Inspector Andrew Grant of Brent CID said: "This will be the fifth Christmas Robert's family have spent without him and I would again urge members of the public to come forward with any information that will help us find him.
"I would also like to appeal to Robert and let him know that I'm here for him. If you're in any trouble, please call us or your family and we will help you. We just want to know you are safe and well."
At the time of his disappearance Robert was described as a white man, approximately 5ft 7ins in height and of slim build with short brown hair.
Although Robert is known to frequent the Holloway, Kentish Town, Islington and Camden areas, he has been missing for five years and could be living anywhere now.
