There is to be an inquiry into the police DNA database following fears its use could be extended to speeding drivers and litterbugs.
Government advisers the Human Genetics Commission are to oversee an inquiry into the way DNA records are used in the fight against crime.
The system has already been criticised for being too large and unfairly targeting ethnic people.
A large number of innocent people have found themselves on the database, which is said to be the largest in the world.
Last year it was reported police are seeking powers to take DNA samples for non-imprisonable offences such as speeding.
HGC chairman Sir John Sulston said: 'The police in England and Wales have powers to take a DNA sample from anyone arrested or detained on suspicion of a wide variety of offences, from serious crimes like murder and rape to begging or poaching.
'These powers to take DNA without consent are much stronger than in any other country and it has been suggested that they might be extended even further, to include offences such as speeding and dropping litter.
'There is an important balance to be struck between individual rights and public safety and we need to know how people feel about these issues.'
The inquiry’s conclusions are expected to be published in Spring.
