A Cambridgeshire police sergeant who called himself 'Daddy' in a work WhatsApp group asked a colleague if a female suspect had 'any nudes' on her phone, a court heard.Paul Street, 41, allegedly assaulted a suspect with a baton, mocked a 17-year-old boy who was strip-searched and requested a sexual video from a suspect's phone, all while fostering a 'toxic' work culture.The former sergeant led a team at Cambourne Police Station that tackled county lines smuggling and organised crime, but he was exposed after anti-corruption officers seized his phones in 2021.Two WhatsApp groups were uncovered on his devices that prosecutor Anne Whyte KC said demonstrated a 'zero tolerance attitude to anyone on his team who disagreed with his methods.'One group was called 'Impact Team' where he referred to himself as 'daddy' and a smaller 'Inner Circle' group was created to share 'highly negative and inappropriate' comments about colleagues, the court heard. In Autumn 2020, PC Josh Williams, 38, told Street he was examining the phone of a female suspect that was 'quite fit'.Street allegedly asked if she had 'any nudes' to which Williams replied there was a video of the woman committing a sexual act.The WhatsApp chat showed that Williams had saved the photograph of the woman depicting her in underwear and forwarded it to Street. Former Cambridgeshire police sergeant Paul Street pictured outside the Old Bailey yesterday Street has been charged with assault occasioning actual bodily harm, perverting the course of justice and two counts of misconduct in public officeA year later, Street asked Williams if he still had the intimate private video because he wanted to show 'the lads from footy', the court heard. Williams replied: 'I doubt it mate sorry. You exhausted all other porn?'Ms Whyte told the jurors: 'It was no part of Josh Williams’ job to reveal and discuss private images and potentially an explicit private video. 'It was no part of Paul Street’s job to ask for nudes, to look at the images and later to ask for the video.'Williams pleaded guilty to misconduct in public office, the Old Bailey heard.No charges were brought against the woman, who cannot be named for legal reasons. Street was also accused of knocking Samuel Kayode to the ground and punching him in the face after he evaded arrest in January 2020.It is alleged that the sergeant took a 'trophy' photograph of the injured suspect and sent it to 17 colleagues on the Impact Team WhatsApp and told them: 'he had a disagreement with my baton and then my fist.'A new officer reported the WhatsApp messages to a chief inspector and Street was issued with an action plan but he remained in his post.In his statement, Street claimed he acted in self-defence after Kayode ran at him.Mr Kayode, who later made a formal complaint, was jailed after pleading guilty to possession of drugs with intent to supply.Ms Whyte said Street 'lost all sight of how to conduct himself' and was 'out of control.' Three months later, 17-year-old Robiul Islam, who Street allegedly referred to as an 'absolute g*bshite', was arrested and strip-searched.The court heard that Street said he would like to bully him 'relentlessly' and encouraged another officer to 'please hit him'. Street even recorded a video of himself addressing the suspect saying police were going to his mother’s house to 'rip it apart', the court heard. He allegedly told his partner: 'had a rumble with our drug dealer in the cell today. Little rat has proper pressed my buttons today.'Islam was charged with possession of Class A drugs and using insulting words and behaviour for which he was fined £300.Prosecutor Anne Whyte KC said Street 'was not just promoting inappropriate attitudes, he was positively creating a toxic culture which junior officers would find difficult to challenge and likely to adopt.'She told jurors: 'It may be that Paul Street will try to depict himself as a maverick, unorthodox officer whose own particular brand of messaging is one big institutional joke.'Street has been charged with assault occasioning actual bodily harm, perverting the course of justice and two counts of misconduct in public office, all of which he denies. The trial continues.
