Kenneth Farr's widow Helen said his death was "pointless"

Kenneth Farr, 37, died in 2002, when an unsecured car park barrier smashed through his car windscreen at the Asda store in Cardiff Bay.

An inquest jury found that Mr Farr from Penarth had been unlawfully killed.

South Wales Police said that a review into the case will be undertaken following the jury's verdict.

Detective Superintendent Dave Bishop, of South Wales Police, said the investigation team would look again at the evidence.

"In view of the verdict of unlawful killing, the Crown Prosecution Service, South Wales Police and the local Environmental Health Department will review the sufficiency of the evidence, and consider any future prosecution," he said.

"Our thoughts remain with the family of Mr Farr at this time."

Ken has missed the first words of his youngest daughter and the first day at school of another Helen Farr

Mr Farr, an electronics engineer, who had gone to the store to buy a garden shed, was travelling with his three-year-old daughter at the time of the incident. She was unharmed.

But his widow, Helen, has said that the loss of her husband and the father of three had been "difficult" for the family.

"My husband's death was pointless and futile and totally avoidable," she said.

"Ken was a lovely family man who totally idolised his daughters and has been greatly missed since this happened.

"It's been difficult to get through but we have had to do it for the children. "But Ken has missed the first words of his youngest daughter and the first day at school of another."

The youngest of Mr Farr's three daughters was in the car

She said that now when she drives around she notices car park barriers to see whether they are properly secure.

"Really, these gates are lethal and should not be in existence. They should be removed, especially if people do not pay any attention to securing them," she said.

"The next thing now really from our viewpoint is the prosecution of Asda."

But Asda has said it intends to seek a judicial review to reverse the verdict of unlawful killing reached by the inquest jury.

The company has said that it believed the jury should not have been given the option of unlawful killing.

"In the light of this meticulous investigation, it is simply unjust that the inquest jury were permitted to consider an unlawful killing verdict - especially as an inquest is designed to find out facts, not apportion blame," said Nick Agarwal from Asda.

"We are just as upset today at the tragic death of Mr Farr as we were in 2002,"

"We continue to express our sympathies to Mrs Farr and her family."

The padlock on the barrier was broken, the inquest heard

The Cardiff inquest, which lasted for two weeks, heard how Mr Farr was hit on the head when a swing steel barrier was blown into the path of his car by a gust of wind as he drove into the supermarket car park.

It crashed through his windscreen striking him on the head before going through the driver's side window.

He was pronounced dead in hospital following the incident.

The jury heard how the barrier in the car park had not been properly secured and witnesses reported seeing it swinging in the wind.

The court also heard about two similar incidents at other Asda stores when barriers had struck cars, and in one case Asda was fined for breaching health and safety regulations.

Since the accident, all similar security barriers have been removed from Asda car parks throughout the UK, the inquest was told.
