Burglars took car keys from inside a home as the owners slept upstairs and made off with their two cars.
The crooks also took a wallet, mobile phone, handbag and purse with a butterfly pattern when they struck at the home in Pipit Close, Flitwick last Wednesday (December 23) between 1.15am and 5.30am.
The vehicles taken were a black Audi A4 registration YL07 MVR and a silver Ford Focus registration Y951 KGM which were parked outside.
PC Jonathan Gordon said: “This was obviously a very distressing crime in which two cars were stolen while the victims were asleep in the house.
“I would urge anyone with any information, or has seen either vehicle since the break in, to call police.”
Anyone with any information should call PC Gordon on 101 or Crimestoppers, anonymously, on 0800 555111.
