The identity of the British soldier who allegedly stabbed a Kenyan mother to death before dumping her body in a hotel septic tank after a night of partying in 2012 is widely known in the army, it has been claimed.
The naked body of Agnes Wanjiru, 21, who left behind a five-month-old daughter, was found at the Lions Court Inn hotel in Nanyuki nearly a decade ago by a maintenance worker who noticed a foul smell.
The sex worker's family has since been pushing for answers and claims British and Kenyan authorities have staged a cover-up to maintain diplomatic relations over the nearby Nanyuki army base, where the UK sends six infantry battalions a year for eight-week exercises.
But following an investigation by The Sunday Times, soldiers who took part in the drunken and debauched night of group sex with local prostitutes said they were shown Agnes' body that evening by her alleged killer, named by the paper as Soldier X.
Another soldier from the Duke of Lancaster regiment, identified as Soldier Y, said: 'He took me to the tank and lifted it up, and I looked in and I just remember seeing her in there. My heart sank. My mind just went blank. The only thing I could say to him was: 'I'll never forgive you for this.''
The resurfaced allegations have prompted a new murder probe by the British Royal Military Police, while a Labour MP has called on the Government to investigate any possible cover-up.

Agnes' body lay in the tank for two months before it was discovered, by which time the British troops had long since departed Kenya.
Members of the regiment allege the name of her killer was an open secret, with five different soldiers identifying the same person to the Sunday Times.
But the British Army has never held an inquiry and none of those present on the night have been questioned by superiors.
An inquest was held in Kenya in 2019 in which a judge ruled the mother was 'murdered by British soldiers' but no subsequent action was taken by the army.
Soldier Y has also accused the army of a cover-up, saying he told 'the proper people' about the alleged killing.
He said: 'Everyone. All the lads, all the senior command that were there. I went to higher up, hierarchy, people that should have dealt with it. I got called a liar. They basically just said, 'Shut up and get out.''
Soldier Y says he is prepared to go to the British police and go on the record and is even willing to go to jail himself to ensure justice is served.
He recalls Soldier X bursting into the bar where the other soldiers were partying and appeared visibly distressed, saying: 'Help me, help me.... I've killed her'.
He then escorted a group of them to the septic tank behind one of the hotel's lodges where he opened the lid and showed the young mother's body.

Soldier Y says he returned to the bar and told others about what he'd seen before the evening was cut short by RMP who turned up and scolded the soldiers for sneaking out of their base.
He claims that when he returned to camp, he told senior officers about what had happened at the hotel while Soldier X remained silent.
But no action was taken and neither he nor others present at the hotel were ever questioned by the army, he says.
Another in the regiment, Soldier Z, said Soldier X told colleagues he had killed Agnes by accident during sex after choking her.
The belief that it was an accident may have led to other soldiers keeping quiet about the incident because of the 'code of silence' in the army.
It later transpired that Agnes had been stabbed to death, and she also suffered blunt force injury to her chest and her lungs had collapsed.
Soldier Z said: 'We thought she choked during sex, that it was an accident. That's completely different from stabbing someone to death and putting them in a septic tank.'
Soldier Y says he does not recall the sex game story and says he does not know what happened, other than: 'He definitely did it. A thousand per cent, it was him.'
Six days after Agnes' disappearance, the regiment returned to the UK and rumours started to spread about the killing.
The regiment was then deployed to Afghanistan, with the killer's identity then common knowledge.
Kenya's police inquiry was opened in 2012 after the discovery of the body.
