Scientists close net on rapists using condoms
Police have seen a rise in cases in which sex offenders use protection, in a bid to avoid sexually transmitted diseases and to make sure they don't leave DNA evidence behind.
But a technique developed by academics at Sheffield Hallam University will enable forensic specialists to detect condom lubricant on fingermarks left at crime scenes.

Dr Simona Francese, from the university's Biomedical Research Centre, said: "If condom lubricant can be detected in fingermarks it would improve the evidence for the prosecution by establishing the assailant's presence at the scene and, crucially, having had contact with a condom."
The BMRC research is published in the journal Rapid Communications in Mass Spectrometry.
