Tamara Ecclestone's home security information was all available online in the lead up to her £50million burglary, and it may have made her a target.
The Formula 1 heiress, whose father is Bernie Ecclestone was robbed of millions of pounds worth of jewellery when thieves broke into the home she shares with husband Jay Rutland.
The couple had applied for planing permission to renovate the £70million house in 2011, and the documents include detailed drawings of the rooms - including the location of a secret safe in Tamara's dressing room.
There was also detailed information about the technology used in the alarm system in the document, which is still publicly available.
The Sun reports that the stolen jewellery was not taken from the safe shown in the drawings, but it may still have made the Kensington home a target for opportunistic thieves.
A source told the publication: “The plans and photos still available to the public are a burglar’s dream.
"They detail every possible entry and escape point as well as the location of Tamara's secret jewellery safe.
“You can apply to have sensitive areas of your home redacted in planning documents."
MirrorOnline has reached out to a rep for Tamara for comment.
Tamara and Jay and their five-year-old daughter Sophia were on holiday at the time of the break in, which is thought to have lasted 50 minutes.
Despite 24-hour security, the thieves managed to make their escape, and Scotland Yard is yet to make arrests.
It's thought that three thieves broke in just hours after the family boarded a private jet to travel to their holiday destination.
Bernie Ecclestone has suggested that it was an "inside job".
He told MailOnline : "I don't have all the facts but, given all the security at the house, I'm assuming it was an inside job.
"It's an awful thing to happen just after she had left the house to go to Lapland. Although maybe it's better that she wasn't in at the time."
The Metropolitan Police said investigators are keeping an open mind about the raid, and that it is being treated as an isolated burglary.
The thieves are believed to have entered through the garden before breaking into safes hidden in the bedroom of the house, which is next to Hyde Park in Central London.
All of Tamara's jewellery is said to have been taken during the raid.
