The driver of a minibus which crashed, killing a man, has been arrested for dangerous driving.

The vehicle was carrying 15 people, including adults with learning difficulties and their carers, northbound along the A23 at Pyecombe when the incident occurred at about 3.40pm on Thursday.

The minibus, which is understood to have been returning to Tower Hamlets, east London, from Brighton, overturned and came to rest in the central reservation, Sussex Police said.

Police named the dead man as Shiraj Ali, 32, of east London. He died at the New East Surrey Hospital.

Three women passengers received serious injuries and are being treated at the Royal Sussex County Hospital. Five other passengers have been released from hospital.

The 43-year-old male driver has been released on police bail.

The crash took place about a mile north of the stretch of road where eight people died in May 2004.

Steve Mohabir, 37, from Godalming, Surrey, who lost his two-year-old son Marcus in that crash and was injured himself, has been campaigning for safety measures along the A23.

He said: "How many more deaths do we need before speed restrictions are put in place?

"Safety cameras would be ideal. Every time someone dies near that stretch it brings back the memory of losing our son."

Gloria Marshall, from Crawley, whose son and daughter died in the crash near Pyecombe, said she heard about the minibus crash on the radio while driving home. She said: "I had shivers running up my spine and was thinking not again'.

"We can't wait for more people to die or more people to be seriously injured before the Highways Agency intervenes.

"The whole stretch of 18 miles from the top of Handcross Hill down to Brighton in both directions needs to be looked at.

"Even if we had a few black and white signs reminding people to kill their speed, that would be a start."

Six weeks ago The Argus revealed that a £40.5 million scheme to improve safety at the Handcross stretch was being delayed until at least 2011.

It has been waiting for an upgrade since the scheme was mooted in the Nineties.

A Regional Transport Board was given responsibility for deciding on a start date for the project at Handcross.

Despite earmarking the scheme as one of six regional priorities, it decided work cannot start until 2011/2012 due to practical considerations, such as design, planning permission, an expected public enquiry and lack of funds.

The A23 was the scene of 20 deaths in 14 months up to July last year.
