A former policewoman lied about her eldest daughter having cancer to get time off work.
Her colleagues set about raising hundreds of pounds to help the family of Rachel Hewitt, 39, of Pontefract, through their dark times.
During the time off Hewitt was helping her two daughters with their showjumping ambitions.
Hewitt, who was an officer with the North Yorkshire Police in Selby, admitted one charge of misconduct in a public office between January 2009 and October 2011 and one charge of fraud when she appeared in Hull Crown Court this week.
Hewitt, 39, told her bosses her daughter was ill with cancer and needed surgery to have a tumour removed. The treatment, she told them, would require taking time off work.
She told her colleagues her eldest daughter had leukaemia and was undergoing chemotherapy. They raised cash to help her.
Hewitt denied another charge of fraud laid in relation to a request for a career break to look after her daughter, but the prosecutor indicated this would not be proceeded with, given the guilty pleas.
The case has been adjourned for a pre-sentence report on Hewitt to be obtained. Sentencing will be on June 6. Hewitt is on bail.
