What we do Advocacy Police Super-Complaints Hestia is a designated body under the police super-complaints system. As we have limited resources, we will only be able to raise policing issues around Domestic Abuse and Modern Slavery. We regret that we are unable to respond to complaints on issues outside these two areas of expertise and on complaints that do not represent systemic issues in policing which are significantly harming the interests of the public. March 2019 Our latest Underground Lives report was the first police super-complaint regarding modern slavery highlighting that police failings when interviewing victims of modern slavery are hindering the prosecution of traffickers and exploiters. In 2018, there was a staggering 250% increase in modern slavery operations by police forces yet only 7% of recorded cases were referred to the Crown Prosecution Service.
