Stuart Cheek, the Hertfordshire Constabulary Sex Offender, has been sentenced to a year in prison for possessing extreme pornographic images.
Chief Inspector Stuart Cheek, 48, who worked for Hertfordshire Police, was found to have illegal images on his phone when officers searched it.
The images included scenes of “acts likely to cause serious harm and bestiality”, the Crown Prosecution Service (CPS) said.
He was found guilty of two counts of possessing extreme pornography.
Stuart Cheek was convicted of one count of unauthorised access to computer material at Cambridge Crown Court in July.
The CPS said an audit found Stuart Cheek had “accessed several files on several police systems without a legitimate policing purpose”.
Stuart Cheek was sentenced to 12 months’ imprisonment at Aylesbury Crown Court.
The illegal images were sent and received on a WhatsApp account under the display name “Cheeky”, the CPS said.
Clare Forsdike, district crown prosecutor from the East of England complex casework unit, said: “The sharing and viewing of images of extreme pornography is not a victimless crime.
“Stuart Cheek’s actions were an abuse of power and a criminal act.
