Dawn Copley, the acting chief constable of South Yorkshire Police, has stepped down just one day after taking up the role following news that her conduct at a previous force was being investigated.
Copley yesterday replaced David Crompton, who was suspended over his response to Hillsborough
On Tuesday, a jury found that 96 Liverpool fans who died in Sheffield at a 1989 football match were unlawfully killed and that there were police failings.
South Yorkshire's Police and Crime Commissioner Dr Alan Billings said that Copley's decision was due to her not wanting "any further negative publicity or criticism to be levelled at the force".
Her conduct is being investigated by former employer Greater Manchester Police, which confirmed that "an independent investigation was undertaken by Kent Police following a number of allegations".
According to reports, this involved a group of senior officers who were accused of "corrupt practice".
