Detectives investigating a spate of high-value burglaries have released CCTV images of men who might hold important information.
Homes across Dinnington, Brunton Drive, Heaton and Gateshead have been targeted in the past week and due to the "similar nature" of all the incidents they are being treated as linked.
During the latest, in Fenham last night, thieves made off with an estimated £30,000 in jewellery.
Police believe the total value of items stolen during all the burglaries is nearly £100,000.
Det Ch Insp Paul Knox said: "This is very serious offending by a sophisticated and organised criminal gang.
"They have been prolific over the past week and there will be a number of people who would have crossed paths with this gang.
"They aren't from the area, they have Irish accents and it is likely they are staying in some sort of hotel or caravan park.
“We think they could be staying in South Tyneside, and travelling up to the Newcastle area, so we need people across the North East to think about whether they could have encountered these men."
