A KILLER who executed three men after a drug deal went wrong is reportedly suing jail workers, claiming his human rights have been breached.

Kevan Thakrar, of Lomond Way in Stevenage, was jailed for life in 2008 for helping his brother Miran to slaughter Matthew Cowell, 17, his father Keith, 52, and friend Tony Dulieu, 33, with a Mac 10 sub machine gun in Bishop's Stortford.

The brothers were also found guilty of attempting to murder Keith's sister, Christine Jennings, and Matthew's girlfriend, Clare Evans.

The 23-year-old, who was sentenced to a minimum of 35 years behind bars, is reportedly being held at Frankland Prison in County Durham.

According to national press, Thakrar intends to launch civil proceedings against two prison workers at Whitemoor Prison in Cambridgeshire, where he used to be held, because they had "acted unprofessionally" during a routine discussion examining his chances of probation.

The prison officers reportedly wrote him letters of apology, but Thakrar is believed to have discounted them as "meaningless", offended they contained spelling errors.

According to national press, Thakrar's claim for thousands of pounds in compensation is expected to be funded through Legal Aid, and was prompted by the Prisons and Probation Ombudsman Stephen Shaw telling a prisoners' magazine two jail staff had treated a prisoner "unfairly".

Frankland Prison is the maximum security prison where Soham killer Ian Huntley was attacked last month. Huntley needed urgent hospital treatment after a fellow inmate cut his throat.
