In the UK, we have no "poison tree" doctrine so (with limited exceptions) illegally gathering or using evidence doesn't prevent prosecutions. So there is really no incentive NOT to illegally keep data like this. Its also worth noting the UK had a distinction here between illegal (criminal and punishable) and unlawful (not permitted but not a crime either, like say trespassing or taking something that isn't yours accidently). This act is (AFAIK) unlawful. So no police officer can be arrested and personally criminally charged for keeping this data. Its not something you don't have a right to do...
