Teaching assist spared jail despite admitting she had sex with pupil, 15, sent to prison for two years 15:49, 17 Nov 2015 Updated 16:50, 17 Nov 2015 By Steve Robson Caroline Berriman, 30, has been locked up immediately after the Court of Appeal ruled her original sentence was unduly lenient Spared jail: Caroline Berriman admitted having sex with the boy A teaching assistant who was spared jail for having sex with a 15-year-old student has had her sentence quashed. Caroline Berriman, 30, was allowed to walk free from court despite admitting charges of sexual activity with a child, and sexual activity with a child by a person in a position of trust. But today her suspended sentence was quashed and she was locked up for two years after the Court of Appeal decided it was too lenient. The victim, now 17, claimed the pair had sex up to 50 times. He said the abuse has 'scarred him for life' after Berriman let her daughter call him 'dad' and even told him she was pregnant. Outrage: Several individuals complained to the Attorney General about Berriman's suspended sentence The relationship started when she was working as a classroom teaching assistant at Abraham Moss Community School in Crumpsall, Manchester.

He told the Sun: "It must have happened over 50 times in the space of those few months." The teenager says the pair regularly texted and called each other and he spent a lot of time at her Berriman's home. He told the newspaper she even introduced him to her two-year-old daughter, who started to call him 'Dad'. The pupil said the turning point was when Berriman told him she was pregnant. He added: "Stuff like that has scarred me for life." Horror: The victim said Berriman's two-year-old daughter starting calling him 'dad' The boy confided in his older brother, but his mother stumbled upon the relationship and threatened to involve police if her son did not end it. When the student told Berriman his mother knew about their affair, he claims she became angry and attacked him, claiming she would lose her daughter. The teenager claims the teaching assistant turned up at his house with £20,000 in cash begging him to run away with her before he reported the abuse to Childline. Berriman has since left Abraham Moss, having been suspended when the allegations against her were first made. Her suspended sentence prompted outrage and several individuals complained to the Attorney General's Office that it was unduly lenient. Today, three judges in London, headed by Lord Justice Treacy, said a sentence of immediate custody was in all the circumstances "clearly necessary and proportionate". Berriman, of Oldham, Lancashire, was ordered to surrender to her local police station by 6pm. Solicitor General, Robert Buckland QC MP, said today: " Caroline Berriman, who worked as a trusted classroom assistant, groomed and then took advantage of a teenage boy, plainly abusing that position of trust. "I referred the case to the Court of Appeal because the original sentence failed to fully reflect the ages of the defendant and the victim. " I am therefore pleased the Court of Appeal today imposed a 2 year immediate prison term on Berriman which should reassure the public and send out a strong message that teenagers of both genders have a legal right to be protected from grooming and sexual interference."
