A MAN who groomed young girls for sex was caught when the mother of one of his victims found explicit messages from him on her daughter's phone.

James Trigwell was jailed for five years and four months at the High Court in Glasgow.

The unemployed 28-year-old, of West Baldridge Road, Dunfermline, used the Blackberry Message service to contact 21 girls, aged between 13 and 15, and pestered them for photos and sent them obscene messages.

Jailing him, judge Lord Pentland said: "This was a sustained course of sexual offending against young children." Lord Pentland described Trigwell's victims as "emotionally vulnerable" and said he had carried out "calculated and persistent sexual abuse".
