A teacher from Surrey who admitted having sex with a 16-year-old pupil has been jailed for 12 months.
Lauren Cox, 27, of Hazelwood Heights, Oxted, befriended the boy when he was 13 in 2012, after starting work at a school in Bromley, south-east London.
She began a sexual relationship with him in 2015, sending him explicit pictures and videos of herself.
Cox was also placed on the sex offenders register for 10 years by Croydon Crown Court.
She had previously pleaded guilty to five charges of sexual activity with a child under 18 while in a position of trust.
Cox was arrested in September 2015 after the pupil told his parents.
PC Laura Davies, of the Sexual Offences, Exploitation and Child Abuse Command at the Metropolitan Police, said: "Cox abused her position of trust as a teacher and groomed the boy which went on to sexual abuse.
"The abuse has had an extremely adverse effect on the boy with his studies suffering as a result."
