A retired detective has claimed the unsolved murders of a Norfolk couple who were killed 29 years ago could be linked to the deaths of a British family in the French Alps.

The bodies of teachers Paul Bellion, 29, who taught at Thetford's Rosemary Musker High School and his 28-year-old fiancée, Lorraine Glasby, who taught at Diss High School, were found in a field in Brittany in October 1986. They had been shot.

The murder of the couple, from Garboldisham, who were in France on a cycling holiday, remains unsolved and the investigation was dropped in 2006.

Retired detective Pascal Huche, who worked on the case, believes the deaths may be linked to a high profile murder of a family in the French Alps and has handed over the name of a suspect.

The Daily Telegraph has reported Mr Huche believes there maybe a link between the murder of the British-Iraqi al-Hilli family in 2012 and the 1986 killings.

In September 2012, Saad al-Hilli, 50, his wife Iqbal, 47, and her mother, Suhalia al-Allaf, 74, were shot to death in their BMW in a layby near Lake Annecy. The couple's two daughters survived the shooting, which also claimed the life of Sylvain Mollier, a 45-year-old French cyclist.

The four killings remain unsolved.

The Daily Telegraph reported that as well as believing there is a link between the murders, Mr Huche has handed the al-Hilli murder squad the name of a suspect who was never prosecuted over the Brittany case but who later served time for a triple attempted murder in Belgium.

Mr Bellion, a craft and design teacher, and Miss Glasby, a design technology teacher, were reported as missing after they failed to return to their schools, leading to an EDP appeal.
