Twenty six police officers and Police Community Support Officers (PCSOs) serving in Durham and Cleveland have criminal convictions, new figures have revealed.
Freedom of information requests sent to every police force in the UK asked how many police officers and PCSOs had been convicted of criminal offences in the last three years - and how many with criminal convictions still worked for them.
Durham Constabulary confirmed that a male constable was convicted in 2012 for possessing indecent images of children on a personal computer.
A male PCSO was also convicted of common assault on a female member of the public while on duty in 2013.
The force refused to disclose the names of the convicted officers because it would breach the principles of the Data Protection Act.
Durham Constabulary said eight serving police officers and one PCSO had criminal convictions.
Cleveland Police said no serving police officers had been found guilty of a criminal offence in the last four financial years - but 11 serving police officers and six PCSOs have a conviction, as of June 8 this year.
Northumbria Police refused to answer the request, arguing it would exceed the cost limit set out by the Freedom of Information Act.
Forces revealed 309 police officers and police community support officers (PCSOs) were convicted of offences from 2012 to June this year.
But the number of convicted officers is thought to be much higher, as only 25 out of 45 forces provided figures.
