Sutton’s new £3.2m High Street was at the centre of another health and safety controversy after two people were injured in separate accidents in just five days.

On Friday an elderly woman was taken to hospital after tripping up on the new raised “stage” in Trinity Square.

While on Tuesday, a cyclist was left covered in blood with a suspected broken nose in a high speed crash, after failing to see the edge of the same raised section.

The council is currently conducting a review of the whole development, including health and safety concerns.

Councillor Peter Geiringer, who was alerted to the accident involving the elderly woman at 2pm on Friday, said: “It’s dangerous. The council should act to sort this out because there are only going to be more accidents like this.”

At least five compensation claims have been lodged against Sutton Council relating to the High Street since last year’s improvement works.

Warren Moody, who saw the cyclist’s high speed crash at about 11.30pm on Tuesday, said: “The fall was really nasty. He was covered in blood.

“It is obvious how dangerous that section of the square is. It is like an infinity pool – you can’t see the edge until it is too late. Something really needs to be done quickly.”

A spokesman for the London Ambulance Service said they took the woman, in her 70s, to St Helier Hospital with head and back injuries.

Both incidents are the latest in a number accidents, some of which are expected to see Sutton Council have to pay out compensation.

On October 21 an elderly lady was taken to hospital after she fell off one of the log benches. A faulty locking mechanism caused the bench to swing away from under her.

On October 26, a market trader got an electric shock and was taken to hospital after works to power points were carried out as part of the redevelopment.

Sutton Council launched a review in to health and safety issues relating to works as part of an overall review in to complaints made about the project at the end of last year.

Darren Richards, Sutton Council’s executive head of planning and transportation, said: "I was upset to learn of these incidents and would like to apologise to the people involved.

"Without having spoken to them it is hard to know exactly what happened, but accidents happen, especially when you have thousands visiting an area, as we do.

"Safety considerations were an important part of the town centre’s design, and safety audits were carried out and did not raise any significant issues.

"However, in view of the latest incidents, it would be helpful to speak to the people involved to work out what happened and to establish their views on whether additional measures could help highlight the town square’s edges."
