Loved ones of two adult victims of undetected heart conditions have raised nearly £4,000 to help prevent the deaths of other young sufferers.

Dad-of-two Pc Luke Rolfe, aged 30, who worked at Bourneville Lane police station, and Longbridge school girl Alison Linforth, 16, are just two of thousands who have died suddenly when they did not know they were at risk. 

Their friends and relatives want to ensure other families do not suffer the same anguish as them by raising the cash through the Luke Rolfe Memorial Trophy football match for charity CRY - Cardiac Risk in the Young. 

Friend and colleague Pc Simon Williams, from Birmingham South policing unit, said the charity uses money to do heart tests on young people in the community to diagnose defects. 

"It's nice to be able to honour the memory of Luke to show his family that we still care," said Pc Williams. 

"This money will also help other people to hopefully never go through what Luke and Alison's family's had to endure." 

Pc Rolfe was on a family holiday in Florida in August last year. 

While Alison died on her first day at Cadbury Sixth Form College, Kings Norton, in September 2003. 

More than 150 people turned out for the fundraising football match in Pc Rolfe's honour at the Tally Ho! sports ground in Edgbaston, in April. 

They included the police officer's widow Kath and sons Josh, four, and Harry two and Alison's mother Eve, from Northfield. 

Pc Rolfe, who lived in Hereford, served at Edward Road and Sparkhill stations, covering Sparkbrook and Moseley, before moving to Bourneville Lane last April. 

Taking charge of the memorial game was former Premier League referee Alan Wiley.  It resulted in an entertaining game in which Reading beat Hereford 3-2.  The event also included a raffle and charity auction of signed memorabilia. 

Sudden cardiac death affects children and young adults but an underlying inherited condition is often discovered.
