The jury in a murder trial has heard how how the accused "admitted" his guilt in a phone call to his sister while in custody, which was recorded and translated from Urdu.

The six men and six women jurors were also told victim David Read was brutally assaulted in four separate areas in his own flat in Leamington Road, Blackburn.

Giving evidence for the prosecution, a forensic scientist told the jury she found Mr Read's blood on the walls in two areas of the lounge, and two areas of the bedroom in his flat.

Lindsay Meek said this indicated a "prolonged attack", as his killer rained down blows with a hammer and a pair of scissors.

Earlier this week, the jury at Preston Crown Court was told the defendant, Mohammed Ali Khan, 36, had allegedly killed Mr Read in the early hours of June 7 with a hammer and pair of scissors.

The prosecution said he then later tried to cover up his crimes by changing his clothes and discarding items, including Mr Read’s mobile phone, his own blood-stained clothes, and a hammer.

Khan denies the charge of murder.

Ms Meek said extensive blood stains were found on a sofa in the lounge and on the walls behind the sofa, as well as on an armchair.

Ms Meek also said Mr Read’s blood was found on his bed and on the floor of the bedroom close to a radiator.

When examining the bathroom, Ms Meek said bloodstains had also been found here, which were indicative of someone having attempted to wash blood from their hands.

In all, she told the jury Mr Read was assaulted in four different locations in his flat, although it was not possible to determine where the attacks began.

Mr Read had been found by the armchair in the lounge, indicating this was the last place he was set-upon, she added.

Mr Read, 50, was found dead in his flat by his mother, Mary Read, at around 11.20am on June 7.

Khan was arrested on June 9 and charged with Mr Read’s murder on June 12.

After being charged, Khan said: “I never done no murder, there was no intent, I was robbed”, before being told to be quiet.

During his police interview Khan gave "no comment" answers, however the jury heard earlier this week how Khan "made admissions while in custody", during phone conversations he had with family members, including his sister.

The prosecution said while he was in custody at the police station, the defendant made a phone call to a family member, captured on an officer’s body worn camera.

During that call Khan spoke Urdu, and when it was translated it is said Khan had mentioned he had "ruined his life".

The jury heard how he told his family he wanted to go to Pakistan, and said: “What can be done now, it’s all his fault. He did everything to me, I was asleep. What’s done is done now.”

When held in custody following his arrest, Khan made several more calls to his family members, which were recorded and translated.

The prosecution said in one of those calls, to his sister, Khan could be heard to say: "They have everything, they have found the hammer, they have found the clothes which I have thrown, I have thrown the hammer, I have thrown the phone.”

Prosecuting barrister Jaime Hamilton KC told the jury this was "effectively the defendant admitting he had tried to dispose of the evidence in the aftermath of the murder".

In a second call to his sister on June 16, the jury heard Khan has said he’d thrown some black trainers away as they were, “f***ing proof, they were all covered with the blood”.

It was also said he told his sister he could not keep courage as: “I have committed murder.

"Murder has been done by me, what do I do. He stole the stuff worth £700."

Mr Hamilton KC said this was the closest the defendant came to telling the truth, and he made no mention of having to defend himself.

Khan, 36, of Preston New Road, denies murder. The trial continues.
