TWO adults and a child from the same family were in hospital with "very serious" injuries last night after being involved in a horrific accident with a motorbike.

The scene of the crash in London Road, Ipswich, was sealed off while paramedics treated four pedestrians – two adults and two children - and a motorcyclist.

Eyewitnesses spoke of the chaos they found and said they believed the four pedestrians were two grandparents and their young grandsons.

Suffolk police said one of the children suffered very serious injuries and was airlifted straight to Addenbrooke's Hospital in Cambridge.

The two adult pedestrians were taken to Ipswich Hospital, also with very serious injuries. The other child and the motorcyclist were taken to Ipswich Hospital with less serious injuries, a spokesman said.

The accident happened at about 4.30pm yesterday and left a child's bike and a motorcycle in the road.

Traffic officers worked into the night to try to work out what happened in the crash.

Sandra Woods, who lives along London Road, said: "We had come in from the town and I opened my window and saw a motorbike coming up the road and then I heard a bang.

"I thought it must have hit something, like a car. Then there was a build up of traffic. I thought there must have been an accident for it to build up so quickly. I went through the hedge and saw chaos.

"There was a grandmother and grandfather in the road and two grandsons on the side. The motorcyclist was way up the road. He was lying up by the 40mph mark while they were quite some distance away here. Someone said he was conscious and not too bad.

"The boys were just youngsters. They must have been aged about three and six. One of them had a little bike. One man said he gave one of the little boys mouth to mouth.

"The grandparents were in a pretty bad way. She wasn't awake. She was face down in the road and there was masses of blood.

"He was in a pretty bad way but when they put him on the stretcher he was hollering out.

"They were strapping the little boy's leg up. He was the last one to go. The other one had blood in his hair.

"It was just dreadful. It is one of the worst I have seen in a long time."

The road was closed at the junction with Robin Drive while the emergency services dealt with the accident.
