A woman sexually assaulted by Soham killer Ian Huntley has been protesting from the rooftop of Hull College over the police treatment of her case.
Miss Giblin first reported the incident to police in 1998
Hailey Giblin threw leaflets from the Queens Gardens campus, to campaign against Humberside Police's failure to prosecute Huntley.
Last year Mrs Giblin won a civil action after the killer admitted sexually assaulting her when she was aged 11.
A spokesman for Humberside Police said Mrs Giblin had been arrested.
In an email to the BBC, the 21-year-old said her cries for help had "fallen on deaf heartless ears".
She said: "The demand that I make is that Humberside Police arrest and charge Ian Huntley for sexually abusing me in 1997 within the next seven days and [if they fail to do so] to pass the case file to a force that is more capable.
"I have fought for almost half of my life for justice".
Mrs Giblin began her protest at 0820 GMT and large crowds gathered outside the college campus to watch.
A spokesman for Hull College added: "The college has ensured the safety of staff and students by deciding to close the Queen's Gardens campus from lunchtime to enable the police to deal with the incident.
