A couple who had a purely sexual relationship after meeting on Tinder fell out in a big way when she accused him of assault.

Sarah Baker claimed Peter Cooper, 48, had pushed her over twice banging her head and back on his boat the Luna moored in Mylor Yacht Harbour, Mylor Churchtown.

But following a trial at Truro Magistrates Court today, the bench decided that the case had not been proved beyond reasonable doubt and found him not guilty.

Defending Cooper, solicitor Fred Howell said his client never assaulted Ms Baker and that she was exaggerating the facts.

Magistrates heard that the couple had met on the online dating app and had formed a relationship based purely on sex.

On the night of February 19 last year, the court heard Mr Cooper contacted Sarah Baker and invited her onto his boat moored on the pontoon at the harbour where he lived.

The couple had drunk half a bottle of rum and a few glasses of wine between them before having sex.

Sarah Baker claimed that Mr Cooper became angry and aggressive when she refused to have sex a second time - although Mr Cooper later said it was he who did not want to have sex again.

A short video filmed by Mr Cooper on his phone and shown to the court, didn't show any assault but the couple were heard drunkenly arguing before there is a thud and scream and Ms Baker crying saying "F**king Hell you whacked my head."

Giving evidence screened from Mr Cooper she told the court that she was scared by Mr Cooper's aggression.

She claimed he started to shout and swear and call her names told her she couldn't stay on the boat despite the fact she was in no fit state to drive.

"I got my stuff and he was shouting at me," she said. "I turned round to face him and he shoved me and I went flying through the door and down the drop onto my back.

"He pushed me quite hard and I shouted 'You've hurt my back' straight away."

She phoned a male friend to come and get her and claimed as she was going out onto the upper deck Mr Cooper had shoved her again and she hit her head on a door frame. All this happened in the early hours of February 20.

She got off the boat and walked along the pontoon and was found by the harbour security guard in distress who advised her to call the police which she did. He then waited with her until her friend arrived and then so did the police.

From the witness box Mr Cooper said he had never assaulted Ms Baker and denied pushing her. He said it was she who had been quite aggressive and "lairy" after he told her that he didn't want to have sex with her for a second time.

He said she made threats as to what she was going to tell the police about him and he asked her to leave. He claimed she had fallen over and hurt herself because she was stumbling about.

He said that he had called the police three minutes after she had because he was concerned about what she might say to them.

Finding Cooper not guilty, magistrates said the prosecution's case had not been proved beyond reasonable doubt.
