Female prison warder, 37, faces jail after admitting to an affair with an inmate, 27 Kelly Needham struck up relationship with Martin Gower at HMP Hull Admitted second misconduct charge after failing to report he had a mobile She was caught smuggling his top-up card out of jail to put credit on it By Simon Tomlinson Guilty: Prison warder Kelly Needham (pictured outside Hull Crown Court) faces a jail sentence herself after having an affair with an inmate A female prison warder is facing jail after she admitted having an affair with a male inmate. Kelly Needham, 37, was an officer at HMP Hull when she began a tryst with 27-year-old Martin Gower. She also failed to report he had a mobile phone and was caught smuggling his top-up card out of the prison to put credit on it. Needham pleaded guilty to misconduct in a public office between February 9 and April 29 in relation to the affair. Needham also admitted a further charge of misconduct in a public office as she failed to remove a mobile phone and top-up card from a prisoner and a third count in respect of smuggling the card out of the jail. Staff and fellow prisoners had suspicions about the pair and it led to the fling coming to light earlier this year. Details of Gower's offending were not revealed during the court hearing and she is due to be sentenced next month. She appeared at Hull Crown Court on Friday dressed in a smart suit with her long dark hair tied in a pony tail. Needham's barrister, Richard Thompson said: 'The indictment has been formed in this way as a result of discussions between the defence and the crown.' She was granted bail while a pre-sentence report is prepared by the probation service on the grounds she does not contact Gower or members of his family. Judge Simon Jack told Needham: 'You have now pleaded guilty to the charges and I will adjourn the case for a pre-sentence report so the judge who deals with you has the fullest possible information about you. I will renew your bail, but the fact I am adjourning the case for further reports must not be taken as an indication as to the outcome of this case. These are serious offences and all sentencing options are available. Afterwards, the Prison Service insisted Needham was a rare exception in the prison warden profession. A spokesman said: 'The vast majority of Prison Service staff are honest, hard-working and professional. We are determined to deal with those who are not. Misconduct charge: Needham struck up a relationship with Martin Gower while an officer at HMP Hull (above) HMP Hull is a category B prison holding male inmates in ten residential units including ones for vulnerable prisoners and those convicted of sexual offences. It opened in 1870 for both men and women and ten people were executed there between 1902 and 1934. In 1976, a five-day riot broke out among 100 prisoners in protest at alleged staff brutality which saw the jail close for nearly a year. Ten years later, it lost its status as a maximum security dispersal prison and adopted its current role of a local jail and remand centre. Earlier this year, the Ministry of Justice announced that older parts of the prison will close, reducing its capacity of 760 by 282 places.
