Declan Donnelly's home was targeted by professional thieves while he and his family slept, it has been reported.
Police were dispatched to the West London property shortly before 1am on Tuesday.
The Mirror reports Dec, his wife Ali and their daughter Isla were sleeping upstairs when the burglars attempted to break in.
But the thieves did not gain access to the property and sped away from the scene before police arrived, according to The Sun.
It is understood CCTV from the family home and their neighbours has been taken for further analysis.
The Met Police released the following statement about the incident: “ 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.”
It's believed Dec and Ali were unaware of the incident until the following morning.
A source told The Sun: “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 Mirror reached out to Declan Donnelly's representatives and the MET police for further comment.
