A four-year-old boy who was airlifted off a Cornish beach after a nasty accident has thanked his rescuers.

Little Alistair Hill has drawn a special picture for his heroes, with the help of his older brother Cameron.

The colourful drawing shows three RNLI personnel in a lifeboat.

The boys' family, from Middlesex, have now sent the picture, along with a collage of the incident – headed Ali's big day out – and a £250 donation, to the RNLI.

Alistair was on holiday this summer when the accident happened.

He suffered a suspected spinal injury when he slipped on rocks at Tregonhawke Beach in Whitsand Bay.

RNLI lifeguards gave Alistair emergency help on the beach before he was airlifted off the sands.

Cameron wrote on the bottom of the drawing of the lifeboat: 'Thank you for helping my brother Ali when he hurt his back.'

Their father, Tom Hill, has also written a letter of thanks to the lifeguard team.

He said: 'I just wanted to say thank you for the amazing response and service we received from your organisation – 771 Squadron from Culdrose, HM Coastguard and South West Ambulance were also involved and the professionalism and dovetailing of the services was exceptional.

'Please pass on not only my thanks but also Alistair's to all those involved at the RNLI.'

RNLI lifeguard supervisor Chris Wafer said: 'The whole team was delighted to receive Tom's letter, Alistair's drawing and Cameron's note, and especially the generous donation.

'We were concerned about Alistair after his fall but it was great to hear he's made a full recovery.'
