5 Live Investigates

More than half of all domestic abuse cases investigated by the police result in no action being taken against the offender according to figures obtained by 5 live Investigates. Thirty-three of the forty-three police forces in England and Wales responded to a Freedom of Information request which reveal that 118,000 of the 223,000 domestic abuse cases investigated by those forces went 'undetected.' The programme also has an exclusive report from a pilot scheme in Hampshire where abusers undergo rehabilitation.

As a charity warns children in Britain are facing a silent epidemic of hunger, we reveal youngsters have been treated hundreds of times for malnutrition in hospital. Also, forty years on, solicitors acting for relatives of victims of the Birmingham pub bombings seek an inquest into their deaths in the hope of finding new leads to catch the killers.

The large supermarkets are accused of blighting some town centres by failing to deliver on plans to build new retail facilities. Also, the military fund raisers who're keeping the lion's share of the money they raise. And the probation officers using lie detectors to keep the public safe from sex offenders - but can the technology be trusted?

The government wants to put more offenders on probation. But front-line staff say the re-organisation is causing chaos putting staff and the public at risk.

GPs are being 'prevented' from sending patients directly for early diagnostic tests that would show brain cancer. Some of the CCGs - clinical commissioning groups - in England say only consultants can refer someone for a scan but that can mean a 3 month delay in reaching a diagnosis. The decision to restrict the role of GPs in sending patients for an early brain scan runs counter to a Department of Health push to improve cancer care. The DoH says GPs should be able to send patients directly for a brain scan.

A confidential liquidator's report accuses Scottish Power of reneging on a promise to pay cashback to 600,000 customers who had bought extended warranties. Under the warranty, they could get their money back if they did not make a claim over a five year period. But the companies running the warranty scheme went bust, accusing Scottish Power of failing to honour an undertaking to indemnify cashback pay-outs. Scottish Power denies any improper improper conduct.

Sexting is on the increase among teenagers - and is spreading to primary schools. But are teachers alerting pupils to the dangers of sending intimate selfies to classmates? Also - the woman awarded more than half a million pounds after she was not told of the risks of laser eye surgery to improve her sight. And the call for rail companies to give cash refunds to delayed passengers - not travel vouchers.

The former Director of Public Prosecutions Lord Ken Macdonald says we're still failing victims of disability hate crime - 18 months after a damning review of the criminal justice system recommended an overhaul of how we handle cases. He says that our approach to crimes against the disabled in 2014 is in the same place that race hate crime was before the murder of Stephen Lawrence 21 years ago. He adds the Crown Prosecution Service is still failing to keep accurate records of the crimes and prosecutors aren't pushing hard enough for sentence 'uplifts' in cases where disability is a motivating factor. The CPS says it is about to address the recommendations in the Joint Criminal Justice Review which was published in March 2013.

5live Investigates has exclusive figures which reveal nine out of ten councils no longer provide social care to people whose needs are assessed as 'low' or 'moderate.' This affects people who struggle to wash themselves, dress themselves or perfom basic domestic duties. 500,000 people who would have qualified for social care five years ago can no longer access help from their local authority. The Association of Directors of Adult Social Services which has collated the figures, says the current social care system is 'unsustainable.' The Government says it is investing £3.8 billion pounds in the Better Care Fund which will help more people.
