Thames Valley Police said on Wednesday that the teenager, who cannot be named for legal reasons, is currently in custody. The force added that he is from Bracknell, where the three sexual assaults on young women – including a teenage girl – took place last week in South Hill Park. “Following an investigation by Thames Valley Police, a boy has been arrested on suspicion of sexual assault,” a spokesman said. “The 13-year-old from Bracknell remains in police custody at this time. “His arrest is in relation to sexual assaults which took place in South Hill Park, Bracknell, on July 5 and July 6, in which a teenage girl and two women in their 20s were attacked with their clothing on three separate incidents.”
