My friend was arrested last night, and obliged to give a DNA sample. He was released without charge, and I think he can ask for his DNA sample to be taken off the database - does anyone know about this?
The facts are:
He was stopped by the police while walking home from work because he meets the description of an offender they were looking for (ie race, height, gender, style of dress), they searched him and found that he had a knife in his pocket (which he carries for legitimate reasons: he works for a courier company and uses the knife to slice open packages etc). After arresting him and interviewing him at the police station they released him, agreed that he hadn't done anything wrong and was free to go etc but they had taken a mouth swab for DNA and his fingerprints. I think I read somewhere that if people are released without charge their samples etc are destroyed or at least they can ask that their samples be destroyed.
Anyone know about this?
