Deputy Chief Constable Dawn Copley, who was appointed acting chief constable of South Yorkshire Police after the suspension of David Crompton following the Hillsborough inquest findings, has "offered to step back to her substantive role" while another temporary chief constable is sought, South Yorkshire's Police and Crime Commissioner said.
The new Chief Constable of South Yorkshire police has stepped down after just one day.
Dawn Copley, who has been the force's Deputy Chief Constable since September last year, was appointed to the role on Wednesday.
It came after then Chief Constable David Crompton was suspended - a decision welcomed by the families of Hillsborough victims.
But in a statement tonight, Mrs Copley said she had "offered to step back to her substantive role" while another temporary chief constable was sought.
It follows media reports she is being investigating over her conduct within Greater Manchester Police.
South Yorkshire Police and Crime Commissioner Dr Alan Billings said: "Mrs Copley has made clear to me that she does not want any further negative publicity or criticism to be levelled at the Force.
"In the interests of the Force she has therefore offered to step back to her substantive role to allow me to seek support from the College of Policing in identifying another Chief Officer to act as Temporary Chief Constable until a recruitment process can take place.
"Mrs Copley will need to stay in post for a very short period of time, to deal with pressing matters, but, at her request, this will be for the shortest possible period."
Solicitors acting for 20 of the families said they were "appalled to see the shambles in South Yorkshire Police" following the inquest.
