A detective who gave confidential police intelligence to a drug-dealing childhood friend has been jailed.
Det Con Gary Christie passed on information from the force computer system to the friend, who ran a cocaine operation.
The 42-year-old from Silksworth Lane, Sunderland, was given a two-year sentence at Teesside Crown Court.
Judge Howard Crowson said he had put his friendship above his "principles as a police officer".
He told Christie: "Prison will be difficult for you."
Asa Dobbing, 37, ran a drugs operation in Sunderland and, when a courier was arrested, Christie searched the Northumbria Police computer for details, the court heard.
He made a second search despite a warning by a senior colleague, the court was told.
Christie had been an officer for 20 years and had a certificate of commendation for tackling armed robbers, his defence barrister told the court.
"His career has been valuable to him, important to him, the centre of his life," Christopher Knox said.
Dobbing was convicted of aiding and abetting a person to commit misconduct in a public office.
He is already serving 14 years for drugs offences and was sentenced to an additional year in jail.
