Demirsay Murder: New Appeal
Police investigating the murder of a Bedfordshire grandad, stabbed to death at home in Kempston, have launched a new appeal for information.
Sharif Demirsay, 65, (pictured) who lived with his 68 year old partner at Vineyard Way, was killed on Tuesday 14 May 2013.
He had opened the door to three men who burst in and launched a ferocious attack on him before stealing gold jewellery from his partner's handbag.
Two weeks ago a £10,000 reward was offered for information leading to the arrest and conviction of the killers.
Detectives say that since then they have received a call from a member of the public with more very useful information about the killing.
A man from Cotton End originally arrested the day after the offence has been released from police bail with no charge. Three other men arrested remain on police bail until at least 28 August.
Detective Chief Inspector Tim Redfearn said: "We are closing in on the people responsible for this horrendous crime. The whole of our team is still working on this case, and I remain very optimistic that bit by bit we are moving towards a successful conclusion.
"The most important, and only, thing we can do for Sharif and his family right now is to bring his killers to justice and that's what we will do, even though it may take some time.
"Over the last three months we've been in very close contact with Sharif's family and I know it has felt like a lifetime for them. So the sooner we can resolve this for them, the better.
"For that reason, I'm still urging people to come forward with information. I'm convinced there are people in Kempston who know or have heard more and just haven't realised how crucial their evidence can be in making sure the right individuals end up behind bars."

Police say the murder weapons have still to be found and could have been discarded locally in someone's garden, a hedge or waste ground. As well as the knives, officers also want to hear from anyone who has seen or been offered the stolen gold jewellery.
The high-purity gold Asian-style jewellery is described as:
Eight bangles, high purity gold, six thin and two half-inch wide, all with designs on the outside.
One plain heavy gold ring
Three rings with imitation stones ~ one with a green and a white stone, one with a large red stone with other white stones, and one with green, red and white stones.
A pair of drop earrings, with bell-shaped bottoms
Two chains, one chain with a leaf design all over and other with a bead on it
Gold earrings with red stones and cut-out design
Anyone with information is asked to contact Bedfordshire Police on the non-emergency number 101.
