A Central Criminal Court judge has accepted that he cannot review the sentence he imposed on one of the two men who murdered schoolgirl Ana Kriegel when they were just 13 years old.

The case of Boy B, now aged 21 and who cannot be named due to protections for underage offenders under the Children Act, was raised today before Mr Justice Paul McDermott.
