Lostprophets frontman Ian Watkins is facing child sex charges.
The 35-year-old rocker, from Pontypridd, Wales, has been charged with conspiracy to engage in sexual activity with a female under 13 and possession/distribution of indecent images of children.
He was questioned at Cardiff Bay police station in his native Wales and is due to appear at a magistrates' court in the city on Wednesday.
A spokesman for South Wales Police says, "A Pontypridd man has been charged with sexual offences against children and is due to appear at Cardiff Magistrates' Court today.
