Peterborough travellers' site shootings: Three 'serious but stable'

A car strewn with bullets was removed from the scene

Three men remain in a "serious but stable" condition in hospital after being shot at a travellers' site in Cambridgeshire.

The men, aged 41, 43 and 46, were injured in an incident in Oxney Road, Peterborough, shortly after 10:00 BST on Monday.

Police are currently examining evidence removed from the scene including a car with gunshot damage.

The shooting is being treated as an isolated incident.

BBC Look East's Sally Chidzoy reporting from the scene said a Ford Focus was seen being transported from the site "with what appeared to be gunshot damage to the windscreen, the side of the car, and... the rear windscreen appears to have been shot out".

Travellers on the site have also spoken of the men being shot in caravans.

Two of the men are said to be in critical condition

"The travellers are loathe to go on camera... but those that have spoken to us say it's clear to them that this was a grudge attack," she added.

A police spokesman said they were "keeping an open mind" about the motive for the attack.

The injured men are being treated at hospitals in Cambridge and Peterborough.

An air ambulance took one of the men to hospital.

East of England Ambulance Service spokesman Gary Sanderson said: "Three men were treated at the scene for ballistic-type injuries, two of which are deemed serious."
