Road safety campaigner Mr Spiller has been arrested accused for 'running over neighbour'
Lib Dem councillor Ian Spiller, 35, is accused of using his car as a weapon to leave a 39-year-old neighbour in hospital.

But the double-glazing salesman was arrested in connection with a car attack on his new build housing estate which left the victim in hospital with serious injuries.

A spokesman for South Wales Police said confirmed they were investigating a crash on Ton Tylluan, Broadlands, Bridgend, on Saturday 11 February.
The spokesman added: “A 35-year-old man was arrested on suspicion of wounding with intent and has been released on bail.”
The day after the crash, Mr Spiller stepped down as a councillor told his Facebook followers he was standing down from the role due to a “personal tragedy.”
The 39-year-old victim is understood to be in a serious, but stable condition at the Princess of Wales Hospital, Bridgend.

Mr Spiller wanted to lower the speed limit on the A48 near his home in Bridgend from 60 to 40miles per hour and campaigned to stop vehicles turning right on a busy road.
Mr Spiller tried to raise money and awareness following the death of 16-year-old Rhys Rubery who was making his way home from a day out at the beach when he was hit by a motorcycle and thrown under a car.
Rhys was later airlifted to hospital with traumatic brain injury and died the following day after his condition failed to improve.

His inquest heard he may not have seen the motorbike that struck him on the 60mph limit road.
Spiller wrote to Bridgend County Council following Rhys' death pleading for them to reduce speed on the road and make a safe pedestrian crossing.
His “Make it Safe” campaign has been one of his main features of his work on Laleston Community Council where he serves as a Lib Dem councillor.
Spiller refused to comment about his arrest.
