Police are appealing to the public for any information about the disappearance of a Kilburn man who went missing four years ago today.
Robert Duff, 41 (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 birthday.
Robert's family, including his two daughters, are distraught and extremely worried for his welfare.
In a statement Robert's family said: "We miss Robert terribly and he is constantly in our thoughts. The hardest thing is not knowing where he is or what has happened to him. Hearing his voicemail message is all we have. Someone must know something about Robert's disappearance and our whole family is making this plea to urge anyone who does know anything to end this hell for us by sharing any information they know."
Detective Inspector Lee Dawson of Brent's Public Protection Group said: "I urge anyone with any information at all on the whereabouts of Robert to call us immediately. This is a very distressing time for Robert's family so please help them by coming forward with any information that will help us trace Robert, no matter how old this information is or how small it may seem.
"I also appeal to Robert - if you are in any trouble then we can help you, just call your family or the police and let us know you are safe."
The last sighting of Robert was confirmed from CCTV footage showing him withdrawing money from an ATM outside of Sainsbury's, in Holloway Road, at about 11:12hrs on 12 January 2013.
Robert is described as a white man, around 5ft7ins to 5ft8ins tall, of slim build with short brown hair.
Robert is known to frequent the Holloway, Kentish Town, Islington and Camden areas, however at this stage Robert has been missing for four years and may have visited other areas.
Anyone with any information about the circumstances of Robert's disappearance, the events leading up to his disappearance or any information since his disappearance, should call Brent's Missing Persons Unit on 020 8733 3734 or 020 8733 3092 - alternatively contact Missing People on 116 000.
