More than 600 sex offenders are living in the community in Norfolk.

From Monday, if you think someone you know is one of them, you can check with Norfolk Police.

As part of this scheme, they've got to tell you - but only if a child is in danger.

It's called a disclosure programme, and the information you find out has got to be kept confidential.

Listen to KL.FM news throughout the day for more info on this - and there'll be special report in the extended news at 1pm.
