AN attractive young mother lured a 24-year-old music teacher to a secluded rendezvous with a promise of sex after meeting him on an internet chatline.

They arranged to meet at The Glades centre in Kidderminster at night last May where she took him to a "discreet" area, said prosecutor Charles Hardy.

He gave her £40, expecting her to perform a sex act but was set upon by two men who had been hiding in the bushes.

Judge John Cavell, who sentenced all three to three years detention, said: "There can be no doubt this was a carefully planned robbery. The victim was lured on the pretext that sexual activity would take place." The victim had been left angry, upset and humiliated.

Olivia Windridge, 19, of Lisle Avenue, Liam Moody, 20, of Brinton Crescent and Thomas Freeman, 20, of Hurcott Road, all Kidderminster, pleaded guilty at Worcester Crown Court to the robbery.

Mr Hardy said there had been numerous discussions about sex on the chatline between Windridge and her victim. When they met at 10pm on May 19, he gave her £40 and was partly undressed when he was attacked.

He heard the phut of a ballbearing gun and was hit on the head and leg with a stick. His attackers went through his pockets and took his wallet and bank cards.

When they left, he was warned: "Don't call the police or we will come back for you." But he contacted the police from his car and two of the attackers were found in undergrowth at the bottom of Comberton Hill. Moody had the victim's driving licence.

Windridge was arrested at her home at 1am the next day, said Mr Hardy. She admitted it was a "sex for money" arrangement, although she did not intend to have sex. Her companions were there to protect her.

Moody admitted having a pump action bb shotgun, which had been fired but had not hit anything. Freeman, Windridge's ex-boyfriend, said he had used a stick in the assault.

Freeman had nine previous convictions for 15 offences, including battery and theft, said Mr Hardy. His co-defendants had no convictions.

Sophie Lomas, for Windridge, said she had given birth before Christmas to a nine-week premature boy and she had a one-year-old child as well.

She had difficulty with relationships and at one time had nowhere to live and was suffering from a lack of money.

Moody, said Jason Aris, was susceptible to negative influences but had been genuinely remorseful for his involvement.

Charles Hobbs said Freeman had given little thought before embarking on the enterprise but although he suffered from depression, he had matured since being remanded in custody.

The judge ordered that the 175 days Freeman had spent in custody on remand should count against his sentence.
