The thieves broke into the home in Greengarth, St Ives, between 5.20pm and 7.55pm on Thursday, September 12. When the victims returned they found the house had been searched and several rings had been taken. It is believed the burglars left in a white vehicle, possibly a BMW. PC Andy Minns, investigating, said: The victims have been left very upset by the burglary and I would urge anyone with information to come forward. We are particularly keen to trace the white vehicle which was seen driving off towards Pig Lane. Anyone with information should call PC Minns on 101.
