Fourth arrest over Sharif Demirsay killing in Kempston
An 18-year-old man has been arrested on suspicion of murdering a grandfather who was stabbed to death at his Bedfordshire home.
Sharif Demirsay, 65, died after three men armed with knives forced their way into Vineyard Way, Kempston, at 21:30 BST on 14 May and attacked him.
Officers went an address in Kempston on Thursday night and arrested a man.
He is the fourth to be arrested in connection with the case, said Bedfordshire Police.
He will be interviewed by detectives from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit.
On Tuesday two men, aged 17 and 19, were arrested in Kempston on suspicion of murder and were released on police bail pending further enquiries.
A 24-year-old man arrested in May on suspicion of murder has been bailed until the end of July.
Det Insp Richard Wall said: "We still believe there are people locally in Kempston who have information about those responsible for carrying out this terrible crime on a defenceless elderly man.
"For the sake of his family and the wider community, I urge you to be brave and come forward if you can help. The people responsible for this murder must be brought to justice."
