A man dubbed the Kalashnikov Killer after blasting a man to death with an assault rifle has been secretly rehomed in a quiet Sussex cul-de-sac.

Neighbours living in the historic town of Arundel were "unnerved" yesterday to learn psychopath Noel Ruddle - controversially released from a Scottish prison four years ago because doctors could not treat him - was living among them.

Ruddle, 47, was jailed for shooting dead neighbour James McConville in Glasgow in 1992 with a Gulf War rifle he bought in a pub.

He said voices in his head had told him to do it.

He was convicted on the grounds of diminished responsibility and sent to a top-security psychiatric unit in Lanarkshire.

Ruddle walked free in 1999 after his lawyers exploited a legal loophole saying he was not being giving treatment.

For the past ten months Ruddle has been living in the pretty close, home to families and pensioners.

His new neighbours had expressed fears about his odd behaviour which includes loud arguments on the phone and late-night walks through the streets.

He has changed his appearance since leaving prison, ditching his trademark gold jewellery in favour of a grey beard and flip-flops.

People living in the cul-de-sac said he had made little attempt to get to know anyone since he moved in and did not appear to work.

But none had been told about his convictions.

One neighbour, who asked not to be named when informed of Ruddle's background yesterday, said several neighbours had raised concerns.

She said: "He has always been a bit odd but I put that down to mental health problems. Now I know about his past his behaviour makes more sense.

"I think the authorities should let neighbours know about things like that."

Another neighbour said: "We did think it was a bit odd the council let him live here.

"We did wonder how a single man got housed here as it is mainly elderly people and those with families."

In 2001, in Surrey, Ruddle was also given a three-year community rehabilitation order for threatening to kill a priest. He has claimed he was abused by a priest as a child.

His new home is just a few minutes' walk from Arundel Cathedral.

When approached by The Argus yesterday, a man living at the house said Ruddle had not been there for several months.
