A 17-year-old girl allegedly woke up to find Percy Chikobvu (pictured) had pulled her jeans and pants down to her knees and was 'kissing her lower back and buttock'

A 38-year-old science teacher accused of kissing a 17-year-old's back and buttocks as she slept has claimed his DNA was on her because he 'salivates a lot in bed'.

Percy Chikobvu is accused of sexually assaulting the teenager at his house following a night out.

The court heard how the girl was offered work at Chikobvu's recruitment agency for teachers, which was based at his home.

She was supposed to be mentored by one of Chikobvu's female colleagues but after she began her training, he invited her for a night out in November 2016.

After smoking cannabis and later drinking together at Thirsty in Cambridge they ended up at his house.

Peterborough Crown Court heard how she agreed to stay in his bed with her clothes on.

But she was allegedly woken up by Chikobvu in the early hours of the morning.

In her police interview, shown to jurors, she said: 'I could feel someone pulling down my jeans.

'I've booted him in the chest. I've got up, my bra has been undone.

'I ran downstairs, grabbed my stuff and he came following me down the stairs. He sat on the floor for some reason. I left my stuff at his by accident.

'As I was about to leave, I said, "Percy you're meant to be my boss, you're vile and disgusting"'.

Prosecutor Emma Rance said Chikobvu, who also worked as a science teacher at a school in Northamptonshire, allegedly sent a message to the girl saying: 'Hope you're having a good day I know yesterday was time for us to bond as a team and things didn't go well as we had too much to drink, we are meeting at 6pm, I don't really remember much after that vodka drink lol.'

She added that the prosecution believes it was this message which tried to absolve Chikobvu from his alleged actions.

The court heard how the girl rang her ex-boyfriend shortly after the incident.

She said: 'I told him on Snapchat that my boss just tried to rape me.

'He said, "why were you at all this stuff?" He told me that I was making it up and chatting bulls**t and that I can ruin someone's life.

'I told him about it and he told me I was lying. So I was afraid to tell my mum.'

The girl explained that she eventually told her mother on Sunday November 27, when they reported the incident to police.

The case resumes tomorrow.
