Sentencing ex-policeman Wayne Scott at Newcastle Crown Court, Judge James Goss QC described him as manipulative, controlling and domineering.
"Your offending has had an enormous impact on the wellbeing, confidence and lives of those against whom you offended, destroying their lives," he said.
Scott's offences came to light after he was dismissed by Cleveland Police when a member of the public complained about him touching her sexually while he was on duty.
A former Cleveland Police officer has been sentenced to 19 years in prison for raping two women and sexually assaulting a child. Wayne Scott attacked one of his victims seven times over many years, while he was off duty.
Cleveland Police have urged the public not to approach a sex offender with a history of violence who has failed to register with the authorities.
Police said Geoffrey Mark Ball, 41, is wanted for breach of the notification requirements under the Sexual Offences Act 2003.
Unkempt Ball, who is 5ft 10in tall, of proportionate build and with short black hair, was last seen in a Redcar pub a week ago.
He was convicted of indecently assaulting a woman in 1989 and received six months in custody.
He was then jailed for five weeks in 2010 for sexual assault on an adult female and placed on the Sex Offenders Register until 2017 for this offence.
The public was warned not to approach him as he also has convictions for violence, including a conviction for GBH in 2006, for which he was jailed for four years.
He is known to be a regular user of social media sites and seeks to make contact with people on them.
A police spokeswoman said: "He is also previously known to frequent betting shops and pubs in the Redcar area, and anyone with information regarding his whereabouts is asked to contact police immediately on 999."
Cleveland Police have confirmed that Deputy Chief Constable Derek Bonnard has been dismissed from the force for gross misconduct.
In a disciplinary hearing, six counts of gross misconduct were upheld against Derek Bonnard.
These stemmed from an investigation carried out by the Independent Police Complaints Commission after a referral from Cleveland Police Authority in August 2011.
Derek Bonnard continues to deny strenuously any wrongdoing.
The former Chief Constable of Cleveland Police, Sean Price and suspended Deputy, Derek Bonnard have dropped legal action against three police forces and the man in charge of the investigation into claims of alleged corruption in the force.
Mr Price and Mr Bonnard had previously announced that they would be taking legal proceedings against the police forces providing support to Operation Sacristy, as well as against Keith Bristow - the Director General of the National Crime Agency.
Mr Price and Mr Bonnard had previously claimed that they had been unlawfully arrested and detained, and that their human rights had been both trespassed and breached.
A chief constable accused of using his influence to recruit the daughter of a high-ranking former colleague is to be sacked.
The Independent Police Complaints Commission will disclose the outcome of an investigation into the conduct of Sean Price, the suspended chief of Cleveland Police, on Friday.
An internal disciplinary hearing concluded on Thursday night, and it is understood Price has been found guilty of gross misconduct.
He was investigated following allegations about his role in recruiting the daughter of the former police authority chairman, Dave McLuckie, to a civilian post.
It was claimed Price used "undue influence" to get her the job.
Mr Price has also been investigated for criminal matters as part of the wide-ranging Operation Sacristy inquiry into alleged police misconduct.
The suspended chief constable of Cleveland Police, Sean Price, is to be sacked on Friday after being found guilty of gross misconduct.
