A teacher posed as a 14-year-old girl to falsely brand a colleague a paedophile.

Mother-of-one Sheena Boll rang Childline pretending to be a sexually abused pupil who had had her breast groped by a male teacher.

The 35-year-old worked with the teacher at a school in Newham.

She claimed she was a vulnerable teenager and had been sexually assaulted by the teacher who was taking a such a close personal interest in her that she was afraid to go to school.

After the call in March 2016 police launched an investigation.

During the enquiry other staff at the school praised the accused teacher for the 'positive and effective manner he interacted with his students.'

Boll was arrested three months later and admitted she had made the calls herself.

It emerged that Boll had a history over the past decade of making formal complaints to police against employees of organisations and businesses.

Many were later withdrawn after she told officers she had resolved the disputes privately.

Last week Boll, of Forest Gate, East London admitted malicious communication

In an impact state read to Thames Magistrate Court the victim, who still works at the school, said: 'I found out that an anonymous call had been made to Childline naming me as a paedophile, in that I had groped the breast of a student.

'I just didn't know what to do to convince people that I would never do anything like that to a child - the thought sickens and angers me.

'I felt sick to the stomach and found the whole experience really stressful.

'I felt like my reputation had been tarnished and I was really distressed and even depressed as a result.

'I care a lot about what people think of me and I love teaching and making a positive impact on young lives.'

Last week Boll, of Woodstock Road, Forest Gate, East London admitted malicious communication and was sentenced to 11 weeks prison suspended for two years.

She was tagged and given an overnight curfew for a month as well as a 12 month supervision order.

Boll was also given 200 hours community service and ordered to pay costs and compensation to her victim.

After the hearing Detective Constable Ben Land, from the Met's Sexual Offences Exploitation and Child Abuse Command, said: 'Cases of false claims like this are rare, but do enormous damage to individuals.

'This was a calculated attempt to deceive professionals who are committed to safeguarding the most vulnerable children into believing that this hardworking, dedicated and caring colleague in her school was responsible for abuse against one of their pupils.

'Fortunately Boll's efforts to mask her true identity were unsuccessful and we have received a positive outcome with the conviction and restoration of the professional reputation of the victim.'
