A rapist who was let out of prison on licence sexually abused two women within weeks of his release.

Ashley Shuck, 24, was sentenced this week to a minimum of 10 and a half years after he admitted two counts each of sexual assault and rape and one of kidnap.

He had been allowed out in May after serving four and a half years of an eight-year sentence for an “appalling and terrifying attack” on a 18-year-old woman committed in 2012.

The subsequent attacks took place on 18 June in Kidderminster, Worcestershire. A 28-year-old woman said she was sexually assaulted at her friend’s home, and a 77-year-old woman said she was raped the same morning and then forced to drive around the county for more than two hours.

A serious case review of the management of Shuck’s release has been launched and the case has been referred to the Independent Police Complaints Commission.

Shuck pleaded guilty to the five charges at Hereford crown court on 17 July and was sentenced at Worcester crown court on Monday. He was also given a lifetime sexual harm prevention order and placed on the sex offenders register.

After he was first jailed in November 2012, police expressed the hope that the lengthy sentence would reassure the survivor, who had said she was scared to go to Kidderminster after the attack.

This week, the West Mercia police assistant chief constable Richard Moore said: “Our officers, staff, and partners work together … to provide the best possible protection to the public. In this case, serious further offences have been committed and it is essential that we examine all the circumstances and address any issues arising.”

DCI Mel Paley, of the force, said: “Our thoughts are with the women who have been the victims of sexual assault at the hands of Ashley Shuck. Specialist liaison officers have been supporting them throughout this process and will continue to be available for as long as they are needed.”
