Rebecca Joynes, 30, told the first pupil she abused that 'no one better find out', but the 15-year-old quickly told a friend on Snapchat before secretly taking a photo of the maths teacher and sending it to him.

Arranging an after-school liaison on a Friday, Joynes whisked the youngster - known as Boy A - to Manchester's Trafford Centre where she bought him a £345 Gucci belt from Selfridges - a moment caught on 'crystal clear' CCTV.

She drove him in her white Audi to her one-bedroom flat in trendy Salford Quays where they had sex twice. Word of the liaison spread over the weekend, and on Monday she was sent home from school - with police filmed going to her home to arrest her.

Joynes - who pupils referred to as 'Bunda Becky' - was released on bail, ordered not to contact any child under 18 and suspended from her job.
