A TEENAGER who attempted to murder two schoolgirls while on bail for rape and sexual assault has had his sentence increased to life in prison.

Callum Stroomer was sent down for 17 years after he was convicted of the attack which saw him toy with the blade of a knife and taunt his victims before stabbing them.

However his original sentence was challenged for being too lenient and has now been extended by the Court of Appeal.

Stroomer, of Dee Road, Tilehurst, can now apply for parole after 13 years but may remain behind bars until his death.

The Solicitor General, Robert Buckland QC MP, said: "I referred the original sentence as I felt that it did not properly reflect the severity of the case.

"The offences included the vicious attempted killing of two girls in a violent knife attack, as well as serious rape and sexual assault in circumstances of blackmail.

"I hope this increased sentence gives some comfort to the victims and their families."

At the sentencing on October 23, Judge John Reddihough summarised how Stroomer launched a violent attack on the two-15-year olds - who cannot be named for legal reasons - on March 1 after being repeatedly begged to leave the Bracknell home they were in.

Judge Reddihough said at the hearing at Reading Crown Court: "The defendant stands convicted of very serious sexual and violent offences, the latter attempted murder being committed in the most brutal manner.

"There can be no doubt that in relation to the sexual offences the defendant acted in a manipulative and calculating manner.

"When reading the victim statements it is clear the impact your crimes have had on their lives and the lives of their families."

Stroomer also admitted six sex assaults on two different girls under the age of 16 including two counts of rape.
