FAMILY members have paid tributes to a deaf farmer who was allegedly murdered in a Caerphilly county borough supermarket car park.

Deaf Christopher Gadd, 48, died in Pontllanffraith's Sainsbury's car park yesterday following a collision with a Land Rover.

Police have confirmed that a man has been arrested on suspicion of murder.

Today, Paul Gadd paid tribute to his "salt of the earth" brother.

"I love my brother and I stayed with him until his very last breath," said Mr Gadd.

"People tried to help but there was nothing anyone could do to save him. He's gone and I miss him so much.

"I’ve spent my whole life with him. He had a great sense of humour. He was salt of the earth and he was loyal."

Their fellow brother David, 35, added that it was Christopher's birthday the day before he died.

"We are very close as brothers," he said.

"He went out to get fish and chips for tea and he never came back."

Police say Christopher Gadd was walking outside the store when he was hit by a Land Rover Freelander in Pontllanfraith.

Officers confirmed it is being treated as murder and a man from the Caerphilly area has been arrested for questioning.

Paramedics and an air ambulance were called to the scene where Mr Gadd was pronounced dead.

Sainsbury's said trained staff from the store performed CPR before the Air Ambulance arrived.
