Haley, a 40-year-old resident of Ballard Close, Marden, was sentenced to four years' imprisonment with an extended licence period of a further four years after pleading guilty to multiple charges related to child sexual abuse images and breaches of his Sexual Harm Prevention Order.

Haley had previously been sentenced in 2015 to more than six years imprisonment for a sexual assault and other offenses related to indecent images of children. Upon his release, he was made subject of a Sexual Harm Prevention Order which restricted his use of devices able to access the internet. Any devices he owned would need to be made available for inspection on request by a police officer or staff.

On September 5 last year, officers made an unannounced visit to his home. After examining his phone, police discovered he had been accessing hundreds of illegal images, which included child sexual abuse. Haley would use an online alias, 'Amy', and discuss abusing children with other users. He also used apps to send and receive messages and images, with settings configured to delete after viewing.

Haley was charged with three counts of making indecent images of children and two counts of possessing extreme pornographic images. He was further charged with breaching a sexual harm prevention order and for failing to comply with a notification requirement, relating to the sex offenders register.

He will remain on the sex offenders register indefinitely.

Investigator Lee Sinden, of the Offender Management Unit, said: "Haley had been the subject of strict measures designed to reduce the risk of him reoffending. He has been unable to adhere to these restrictions and has demonstrated a clear determination to access illegal and harmful images, many of which include the horrific abuse of children. "In passing this extended sentence, the judge has recognized he poses a serious risk of further offenses to children. Sexual harm prevention orders are passed by the courts to help protect children and as this case shows, we will do everything we can to ensure those who ignore them face the consequences of their actions."
