TV star Dec Donnelly and his family were left shaken yesterday after “professional” burglars targeted their home.
Police rushed to the £5million property shortly before 1am following a 999 call.
They were foiled by the home’s fortress-like security and sped away from the West London property in a car.
A source said: “Dec and Ali weren’t disturbed. The first they realised anything was amiss was in the morning.”
The burglars fled just moments before police arrived.
Officers rushed to the scene shortly before 1am after receiving a 999 call.
But the suspects — believed to be a “professional” gang — sped off in a car and escaped the officers by a whisker.
The raiders had failed to rip open iron gates at the front of the seven-bedroom home.
Dec and Ali were unaware of the attempted break-in until later when police notified them.
Forensic checks were taking place at the property in West London, yesterday.
Door-to-door inquiries in the upmarket street – where Dec’s TV sidekick Ant McPartlin used to live — were also carried by plain-clothes detectives.
CCTV footage obtained from Dec’s home and neighbours is also being analysed.
Dec’s house watched footage of the crooks in shock as it was played back.
The Met Police said: “Police were called at approximately 00:40hrs to reports of an attempted burglary at a residential property.
“Officers attended. The suspects had left the scene prior to police arrival. There was no evidence that they had gained access to the property.
“Inquiries are ongoing. At this early stage, there have been no arrests.”
Last night a source said: “The robbers couldn’t force the gates open and that’s what made them give up, and flee.
“Dec and Ali weren’t disturbed — the first they realised anything was amiss was in the morning.”
Former Met detective chief inspector Mick Neville, said: “It is quite possible they staked out the address in advance and knew Dec lives there.
“The burglars are probably a professional team if they’re prepared to burgle a celebrity’s home with good CCTV and security.”
Dec bought the house for £1.9million in 2006.
Ant, 45, bought one in the same road that year but moved out after splitting from ex-wife Lisa Armstrong, 44, who still lives there.
Yesterday one of Dec and Ali’s neighbours said: “The police arrived very soon after the car drove off.
“They are lovely neighbours. I hope it doesn’t scare them off from living here.”
Another said burglars raided a home a few doors along from Dec’s a couple of months ago.
There have been 103 burglaries in the fashionable area in just ten months.
Last night a spokesman for Dec declined to comment.
