Police have cracked 64 unsolved crimes following the DNA testing of prisoners and offenders with mental disorders.
Science is playing a crucial role in the fight against crime
A further 78 unsolved crimes are being revisited after an exercise to take samples from 3,772 prisoners and offenders not on a national database.
DNA matches have helped police take action over a 1997 murder in London and a 1994 rape in South Yorkshire.
The success of the exercise, launched in February, was announced on Monday by Home Office minister Hazel Blears.
The DNA samples were taken between January and September before being analysed and loaded into the national DNA database.
The database currently has more than two million DNA profiles.
Around 1,000 profiles are taken from crime scenes each week to try and match them with names on the database.
