THE i360 will reopen this morning after being closed for three days – but mystery still surrounds the cause of the problem.

A full pod of passengers was trapped on Saturday for two hours in the latest breakdown.

The attraction was then closed on Mother’s Day as well as Monday and yesterday.

Bosses would not reveal the cause of the problem, only telling The Argus last night: “British Airways i360 will re-open tomorrow.

“We would like to thank our customers for their patience and look forward to welcoming them back on board.

“We would like to assure our customers that the fault has been resolved and the system has been fully tested.

“The safety and security of our passengers is our number one priority and we would not operate the pod unless it was safe to do so.”

The latest breakdown at the weekend is the eighth incident in just eight month of operation for the long delayed seafront tower.

It is less than a month since the i360 last broke down on February 24.

Passengers, including children, were trapped inside for more than an hour and the tower was closed for five days while a new part was sought.

In December a glitch with the doors on a special Santa ride meant passengers were trapped inside.

And strong winds caused the i360 to close for two days during Storm Angus in September

In September after the pod came grinding to a halt three times in five days architect David Marks promised the problem had been fixed.

It is unclear whether the latest issue is related to the previous problems.

In November Eleanor Harris, the chief executive of Brighton and Hove’s newest tourist attraction, stepped down from the role.

She said she was relinquishing her position to spend more time with her two young children and focus on her own business.

She also blamed Southern for making her miss important time with family in London.

The attraction is yet to appoint a new chief executive.

In January is was revealed that visitor numbers for the first three month of operation were slightly down on predictions.

From August 4 until the end of November, there were 223,127 flights compared with a forecast of 249,020.

The Duke of Edinburgh opened the i360 last October.

The structure, which was designed by the same team behind the London Eye, holds the Guinness World Record for the globe’s most slender tower with a diameter of 13ft (3.9m) at its widest point.
