A couple have spoken of the moment they feared for their lives at the hands of gun-toting robbers who invaded their home.
The husband and wife, who wished to remain anonymous for fear of reprisals, say their lives will never be the same since the terrifying ordeal, which happened on October 19 last year in Northwick Circle, Kenton.
They are appealing to anyone who might recognise the three men who are on the run in CCTV images released this week.
Speaking to the Observer, the 49-year-old mother-of-three told how she was confronted by the gunman.
She said: "I heard my husband calling and heard commotion. I went to walk out of the bedroom but then a man holding a gun walked in. He kept telling me not to look at his face. I hid behind the door but I could still see his hand holding the gun, which was pointing at me.
"You go numb. He wasn't shouting and he was unbelievably calm."
The couple, who are Orthodox Jews, had been preparing a Sabbath dinner for friends who were visiting from Israel.
But at 5.50pm the 49-year-old husband watched the men burst into the kitchen through an unlocked back door. They unplugged the phones, took the back door key and began demanding money.
The insurance consultant, who has lived in the five-bedroom family home with his wife for 12 years, said: "I had to stay calm. The tallest was holding the gun at a right angle and was pointing it at my head like they do in films."
Friends raised the alarm when they arrived at the house and witnessed the harrowing scene through a window in the front door. The couple were then told to lock themselves in an en-suite bathroom while the robbers rummaged through drawers downstairs. They took credit cards and typed the pin numbers in their mobile phones before escaping via the back garden.
The wife said: "It felt like weeks but it was probably only a couple of minutes. They told us they were coming back. I was absolutely sure they were coming back."
Police believe the men travelled to Harlesden by train from Kenton station and tried using a card at an Abbey National cash machine in High Street, Harlesden, but the husband had given the wrong pin number and cancelled the card.
The wife, who works for Great Ormond Street Hospital, said: "Every time another teenager is killed on the streets it brings it back. Someone must know who these people are. We want to put this behind us and make sure this doesn't happen to anyone else. It never goes away and it never will until they are locked up."
