When £2.5m of rare books were stolen in an audacious heist at Feltham in 2017, police wondered, what’s the story?

Everything went exactly to plan. Late on the evening of 29 January 2017, Daniel David and Victor Opariuc parked up and made their way towards the Frontier Forwarding customs warehouse in Feltham, less than a mile from Heathrow. After cutting a hole in the fence, the men made their way to the side of the building and scaled a wall to the roof. There, they cut through a skylight and lowered themselves on to shelving inside the building. The warehouse burglar alarms stayed silent; the men had carefully avoided tripping motion sensors positioned by the doors.

Once inside, with several lookouts posted around the surrounding industrial estate, the men took their time. Over the next five hours and 15 minutes, they broke padlocks off packing cases and placed items inside 16 large holdalls taken from inside the warehouse. The men escaped the same way they had entered: out through the skylight and back into the night.
