Police are appealing for witnesses after linking five West Suffolk burglaries.
Four of the break-ins took place during the day on Friday (June 12).
Three took place in Bury St Edmunds at properties in Abbot Road, Mayfield Road and Grange Walk.
All involved forced entry and, though full details of the stolen items is still being established, police believe jewellery was the target.
A house in Edinburgh Road, Newmarket, was also burgled between 1.50-2.30pm the same day.
Glass in a patio door was smashed and a quantity of jewellery stolen from inside.
The burglars were disturbed by a witness who called police to report seeing suspicious activity.
They escaped by climbing out of an upstairs window and running into Drinkwater Close, where they are thought to have driven-off in a black BMW 640.
They are described as three white men wearing baseball caps.
There was another burglary in Winthrop Road, Bury St Edmunds, some time between Thursday (June 11) and 1pm Saturday (June 13).
Patio doors were forced open and a quantity of cash and jewellery stolen.
Detective Sergeant Claire Burgess, of the Bury Priority Crime Team, said: “We continue to ask members of the public to report any suspicious behaviour they see or hear in their communities.
“Thanks to the vigilant actions of a witness in relation to the burglary in Newmarket, officers were able to disrupt a crime in progress, although the offenders unfortunately managed to evade arrest on this occasion.
“Neighbourhood intelligence can form a key part in helping to solve these crimes and residents are encouraged to report anything they believe to be out of place or unusual.”
Anyone with information about the burglaries is asked to contact the Bury Priority Crime Team on 101 quoting reference NE/15/1008, or Crimestoppers, anonymously, on 0800 555111.
