The inquiry into the murder of a bus passenger stabbed to death by a paranoid schizophrenic man when the victim objected to him throwing chips at his girlfriend yesterday strongly criticised “lackadaisical and nonchalant” attitudes in the criminal justice system.

Research into child killers by Bournemouth University has forced its authors into a contentious conclusion. They believe “Ian Huntley-type” personalities should have to prove they are safe to live among us before they are let out of prison – even if they haven’t killed anyone.

Social services for families in rural Derbyshire have been given a £600,000 boost as part of a council project. The county council is running a three-year pilot scheme which will see a new team of social workers created to cover the Derbyshire Dales.

Nigella Lawson and Sarah Brown opened the first Maggie’s Cancer Care Centre outside Scotland yesterday, marking the launch of a network of facilities across the rest of the UK.

The £3.5m centre, at the Charing Cross Hospital in Hammersmith, London, will provide the same information and advice which is already on offer at the charity’s five existing centres north of the border. It was designed by Lord Rogers, who is responsible for several landmark buildings such as the Millennium Dome and the Pompidou Centre.

Another six centres are planned for England and Wales and are expected to be completed by 2012.

Mrs Brown, who is a patron of Maggie’s, said the new centre would provide a “fantastic service” for cancer sufferers. She added: “These world-class designed centres have offered professional support and information for people in Scotland and it is a tribute to this success that they have been invited to London and other locations in England and Wales.”

Ms Lawson said: “Richard Rogers and his team have created both a stunning piece of architecture and, crucially, an intimate and supportive domestic centre which will have a helpful impact on people living with cancer.”

Police investigating allegations of abuse at a former children’s home in Jersey have arrested a 68-year-old man on the island, they have confirmed.

Jersey Police said the man, who has not been named, was helping with inquiries on a number of historic rape and indecent assault allegations.

More than 100 people have claimed abuse at Haut de la Garenne since the 1960s. Two cellar rooms at the former home are being examined after bone and teeth fragments were found.

Officers have been investigating the four cellars referred to as “punishment rooms” by alleged victims. In 2006, covert investigations began following claims by former residents of sexual and physical abuse of children, dating back to the 1960s.

Earlier this month the case against the first man to be charged in connection with the abuse allegations was adjourned until 12 May.
