A £5,000 reward to catch the culprit of a “senseless” and “unprovoked” attack that left a 64-year-old man paralysed has been put up.

Neville Smith from Harrow Weald was cycling along Bushey Mill Lane shortly before 5pm on May 30 when he was kicked off his bike as he tried to avoid another man cycling toward him.

Crimestoppers today offered a reward for information leading to the arrest of the person responsible, who is described as a white male. They are wanted for grievous bodily harm.

After the attack Neville was admitted to St Mary’s Hospital with “serious spinal injuries” and was unable to feel anything from the chest down.

He then moved to Alderbourne Rehabilitation Unit in Hillingdon where he awaited a bed at the Royal National Orthopaedic Hospital spinal unit in Stanmore.

Neville, who has worked for spinal rehabilitation charity Aspire for 24 years, was praised by his colleagues for his “strong will” and who described the attack on the 64-year-old as “upsetting”.

At the time, director of operations at the charity Tasha Webster said the whole Aspire community had been “shocked” by the incident.

She went on to say Neville is a “well-known and loved” member of the team.

Annabelle Goodenough, eastern regional manager for Crimestoppers, said: “This was a completely unprovoked attack that left an innocent man needing hospital treatment.

“Senseless and heartless is the words that comes to mind when I think about this incident, and now our charity would really like to find who was responsible.

“Contacting Crimestoppers is 100 per cent anonymous. Always. I’d really encourage anyone with information to pick up the phone or complete our secure online form and be a good ambassador for your community.”
