A SIX-YEAR-OLD boy and his grandparents were still fighting for their lives last night following a horrific collision with a motorcycle.

The accident happened in London Road, Ipswich, at about 4.30pm on Thursday and all three are described as being in a critical but stable condition.

The boy's two-year-old brother was in a stable condition, while the motorcyclist was said to be comfortable.

Brian and Christine Seymour and their youngest grandson, Ethan, were being treated in Ipswich Hospital, as was the 24-year-old motorcyclist.

Kieron, the older child, was flown to Cambridge's Addenbrooke's Hospital by air ambulance with serious head injuries.

Shortly after the accident the boys' mother arrived, having turned up to collect her sons, and was heard to cry: "not my boys, not my boys".

It believed the four were on their way home after spending time at Chantry Park.

Betty Wolton, 75, of London Road, is a close neighbour of Mr and Mrs Seymour and witnessed the aftermath of the crash.

She said: "It was dreadful. I can't get it out of my mind. I heard the noise and said to my husband, 'what the hell was that'. It seemed like a car had gone over. There was this grating sound.

"I saw the helicopter come overhead and land in Wren Avenue. It made my stomach turn.

"I feel very sad about it. It's people we know involved and I think that hurts you the most. I feel very sorry for them. I just hope and pray they're ok."

Her husband Albert, 70, added: "I was in my garden when the crash happened yesterday. It must've been about 20 to 30 seconds that this noise was going on. I came out and there was a hell of a lot of mess."

The accident left the road closed for some time after the crash, with diversions set up through the Chantry area.

A small child's tricycle lay in the road marking the scene of the collision.

The motorcyclist, from Ipswich, is believed to have suffered back, hip and leg injuries and lost consciousness for a short time.

Anyone with information about the incident is asked to call Suffolk police on 01473 613500.
