Declan Donnelly’s £5 million-house was reportedly targeted by ‘professional burglars’ on Monday.
Dec, 45, his wife Ali, 43, and their two-year-old daughter Isla were sleeping upstairs when the thieves are said to have attempted to break into the home in West London.
They were reportedly unable to bypass the home’s secure iron gates and escaped moments before the police arrived just before 1am following a 999 call.
The suspects could be part of a “professional” gang, and police were witnessed by neighbours taking forensic checks, making door-to-door inquiries and analysing CCTV footage.
Dec and Ali reportedly were not woken up during the robbery and were unaware until the morning.
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.”
The Met Police released a statement: “Police were called at approximately 00:40hrs to reports of an attempted burglary at a residential property.
