The Yorkshire Ripper has reportedly launched a legal battle for a state pension.
Mass murderer Peter Sutcliffe, who killed a Halifax woman and attacked another during his reign of terror, is said to be taking his case to the European Court of Human Rights.
The 65-year-old, from Bradford, filed a claim against the Government in November, but it was thrown out and he was made to pay £2,000 costs.
Now he is planning to challenge the ruling, according to a national newspaper. If successful, the killer could pocket £137.35 a week in Broadmoor Hospital, where he is currently being held.
He reportedly claims he is entitled to the cash because he paid his taxes before he was jailed.
In 2006, Sutcliffe also applied for and was refused income support of £55 a week. Prisoners are not entitled to benefits.
He was convicted in 1981 of murdering 13 women and attempting to kill seven others from the mid-1970s. In 2010, it was ruled he should never be released.
He killed Halifax Building Society worker Josephine Whitaker, 19, in Savile Park, Halifax, April 1979.
He also attacked another woman, Olive Smelt, in Boothtown in August 1975, but she survived.
