Nine British soldiers are facing questions over the killing of a Kenyan mother who was found stabbed to death in a hotel septic tank in 2012 after a night of partying near an army base.
Agnes Wanjiru, 21, was found two months after her disappearance at the Lions Court Inn hotel in Nanyuki, leaving behind a five-month-old daughter.
Witnesses said the sex worker was seen at the hotel bar that night with a number of British soldiers and left arm-in-arm with one of them.
Her family is now demanding justice and claims her case has been overlooked in a bid to avoid a diplomatic row.
Nanyuki has an army base where, under an agreement with Kenya, the UK can send six infantry battalions a year for eight-week exercises.
As part of the agreement, Kenyan Defence Forces take part in the exercises with their British counterparts.

By the time her body was discovered, the British soldiers had returned home and rumours started about her death, one soldier told The Sunday Times.
Kenyan police identified nine soldiers they wanted to question and asked the British Royal Military Police to interview them and take DNA samples.
But the Ministry of Defence said last week they never received any such request, causing the inquiry to stall.
A new investigation has been opened after an inquest which had been delayed by six years found Agnes was killed unlawfully.
The MoD said last week it is now helping Kenyan authorities 'to determine what support is needed'.
Detectives from Kenya's FBI, the Directorate of Criminal Investigations, visited Agnes' family this February, saying they are still focusing on the same nine suspects, who were they infantrymen, who had booked hotel rooms on the night of her disappearance but were never questioned.
Soldiers recalled it as a debauched evening of 'non-stop' sex with prostitutes for very little money, with a mass brawl taking place the night before between troops, and soldiers were made to get tested for HIV on their return to the UK.

The former infantryman said: 'It was all night, ferrying women back and forth to the rooms, which were like these huts. You could do whatever you wanted.'
But when he returned to the UK he said rumours started, and he heard one soldier boasting about killing a prostitute in Nanyuki.
Agnes' sister Rose Wanyua Wanjiku, 48, said: 'Her case has been completely overlooked. From the first day we reported the case at the police station the police did nothing until her body was accidentally removed from a septic tank.'
She added that when detectives visited her earlier this year, they said they had the names of the nine suspects and would carry out the interviews even if they had to travel to the UK.
Confidential documents seen by The Sunday Times show four witnesses told the original Kenyan police investigation in 2012 that Agnes left the bar with a British soldier and went to his room.
One said they heard a 'fierce row' break out in the room, and the documents show Kenyan detectives asked the
