A 35-year-old Middlesborough, England man is in custody, as officials say he pretended to be pop superstar Justin Bieber online for the purpose of getting teenage girls to perform sex acts on their webcams for his entertainment.

Robert Hunter is accused of inciting a child to engage in sexual activity and making indecent photos, police said, noting some child pornography with both boys and girls as young as 9 was retrieved among the 800 videos confiscated from his home.
