Police say they will work "tirelessly" to identify other victims of the Lostphrophets singer Ian Watkins of Pontypridd who has admitted a series of child sex offences including attempted rape of a baby.
The man who led the investigation at South Wales Police, Detective Chief Inspector Peter Doyle, said the "outcome does not mark the end of our investigations and we will work tirelessly to identify any other victims or witnesses and seek the justice they deserve."
Watkins had denied the charges but changed his pleas to guilty at the start of his trial on Tuesday at Cardiff Crown Court.
“We encourage anyone who has been affected by this case or other cases of child abuse to contact South Wales Police" said Det Ch Supt Doyle.
The public are asked to call either South Wales Police on 029 20634184 or the NSPCC on 0808 800 5000.
