The tenth anniversary of the murder of a have-a-go hero will be marked with a memorial day this weekend.

Mark Webster, 21, was stabbed with a kitchen knife by chef Leroy Griffith as he tried to intervene in an incident outside the Fleece pub, in Addingham, on April 1, 2002.

On Sunday, Craig Minto, from the pub, will host the memorial day to remember Mr Webster and raise money for the Ben Kinsella Trust, set up to promote knife crime awareness and educate youngsters on the consequences of knife crime.

Mr Minto said there were initially thoughts to postpone the event, which will be ten years to the day after Mr Webster’s murder, as a result of the funeral of Jonny English, who died in a car crash in Addingham last weekend.

“The idea is to raise as much money as possible for the Ben Kinsella Trust, while remembering Mark,” he said.

“There will be a band playing, barbecue, bouncy castle, candy floss stand, ice cream stall, tombola and other activities throughout the day.

“We were initially going to put off the day in light of recent events, but after talks with his family and friends we felt it was right to go ahead with it.”

Sunday’s fun day will start at 2pm.

In 2006, a judge ruled Barbados-born Griffith should not be released from jail until 2016 at the earliest.

Griffith turned on crowds of customers after initially arguing with a woman who had hit him with a handbag in the pub’s car park and as others fled screaming, Mr Webster, a plumber, tried to pacify him.

But he paid for his actions when Griffith, now 47, plunged a kitchen knife into his heart and he died within minutes.

Mr Justice Crane, who reviewed the case at London’s Royal Courts of Justice, said the minimum amount of time Griffith must spend behind bars before he can seek parole is 14 years.
