Three men have been arrested after a raid on a luxury London watch shop, during which reality TV star Spencer Matthews was forced to hide in the vault.

The Made in Chelsea star was forced to hide in as armed robbers smashed their way into the store.

A Scotland Yard statement said: “Detectives investigating a smash and grab raid at a jewellery store in Duke Street have made three arrests.

“Police were called at 10:32hrs on Tuesday, 28 May following reports that men armed with weapons drove to the premises on mopeds and smashed a window before stealing goods and fleeing.

“Three men have been arrested on suspicion of armed robbery and remain in custody at a north London police station. A member of the public, aged in his 30s, was treated for a minor injury; this has been assessed as non life threatening or life-changing.”

Thames Valley fire service engineer Paul Starck was left with glass in his eye after the knifeman tried to smash his car window to stop him calling the police.

In a video posted on his Instagram story, Spencer explained that he was at the back of the Duke Street shop when the men made their way in.

“So I just had to hide in a safe, or more like a vault, while this watch shop got smashed to pieces by armed robbers,” he said. “Well maybe not armed robbers, but they had these huge jack hammers.”

“We’re in the back of the shop looking at them, sprint downstairs, hide in the vault,” he said.

He and his friends began looking for the 1991 vintage Rolex Daytona Zenith that Matthews had been hoping to collect, the Press Association reports.

The 30-year-old former Made In Chelsea star went on: “We were looking around and I’m just thinking f****** hell the thing that I’ve been waiting for has obviously just been nicked so I’m going to have to go and get another one.

“Lo and behold we look around and on the floor amongst all the rubble and the glass and stuff there’s one watch in the entire shop and it’s mine. Now if that’s not luck I don’t know what is.”

He said he had been thinking of his wife and son as the drama unfolded, and added: “If they knew that there was a vault downstairs that we were hiding in, and that’s what they wanted, then they would have had to have gone through us to get into the vault.”
