A BULLINGDON prisoner and convicted killer has admitted urinating on a prison guard and spitting at another just one week before he was jailed for a horrifying, fatal acid attack.

Xeneral Imiuru was jailed for 17 years for manslaughter in July last year.

The 20-year old admitted killing Joanne Rand as a result of the attack with a bottle of highly-concentrated sulphuric acid on June 3 2017 in High Wycombe.

Imiuru appeared via video-link from prison at Oxford Crown Court this afternoon to answer one charge of administering a poison or noxious substance with intent and assault by beating.

Both offences took place while he was an inmate at HMP Bullingdon, a prison near Bicester, on July 22 last year, not long before he was handed the jail term for manslaughter.

Prosecutors said that on the first incident he urinated on prison guard Yvette Wright and on the second occasion he spat at a guard named Xena Rose.

His defence barrister Peter Pride told the court that he had carried out the offences to 'in order to be moved off of his wing' while at the prison.

He asked the court to adjourn sentencing while a psychiatric report was prepared and to tie in with other matters he could face.

Judge Peter Ross agreed to adjourn the sentencing hearing and Imiuru was remanded in custody to re-appear at the crown court on March 22.
