A doctor who treated wounded concert-goers has told of how he helped those injured in the Manchester attack.

Penrith-based Theo Weston, a paramedic with the NWAS major incident response team, was among the medics who were desperately trying to help those wounded at the scene.

He was called at 11pm and worked for hours to assist with the emergency response.

While the most serious cases had been dealt with by the time her arrived, Dr Weston joined a number of paramedics, doctors, firefighters and police to do what they could for those that were still at the scene.

"They were limb injuries and there was quite a lot of shrapnel wounds," he said.

"They're talking about nuts and bolts and ball bearings and things. We saw lots of shrapnel wounds in the casualties that were there which on the main are not necessarily life-threatening but they are pretty devastating all the same."

Taking in what he saw following the blast, where the Prime Minister Theresa May has said the attacker deliberately chosen his spot to cause "maximum carnage", Mr Weston said: "It's pretty devastating particularly when the majority of them are younger.

"I have been to five other incidents but I have never been to anything quite as big or as horrific as this.

"As part of our training we plan for this sort of thing, hoping it's never really going to happen, but of course it has."

He said that the response was well run and well organised, adding: "Our thoughts and condolences go to the family and friends of those involved. It difficult for the emergency services but you just can't comprehend what the families are going through."
