Guilty: Colin Andrews, 59, has been jailed for a year . A 'Jekyll and Hyde' police chief who stalked and harassed two women after retiring from the force has been jailed for a year. Former Detective Chief Inspector Colin Andrews, 59, pursued two women despite their protests. He also abused his power to convince them that nobody would believe their words against his. The former officer who worked for Humberside Police for more than 30 years was said to have 'sociopathic tendencies' and was described as a 'controlling, manipulative bully'. After a six-week trial at Manchester Crown Court, he was convicted of witness intimidation, aggravated stalking, harassment and assault occasioning actual bodily harm but was cleared of rape and two other assault charges. The now-disgraced officer from Hessle, East Yorkshire, led a distinguished career solving high-profile murder cases and once tackled a gunman to the ground - but Andrew led a bullying life outside of the force, the court heard. After retiring in 2012, Andrews took up a civilian role as Humberside Police's criminal justice unit manager but struggled to deal with the loss of power resulting from his new position. Both female victims - who can't be named for legal reasons - were pestered by Andrews when they requested he leave them alone. One described how he sat outside her home and phoned her 89 times after bombarding her with over 100 text messages and unwanted presents. He was arrested on August 20 last year after assaulting a man who tried to intervene when he saw Andrews behaving aggressively towards a woman near a park. As Owen Phillips called 999, the former detective slapped him in the face and called him an 'unemployed k******d' even though he was heading to work. When Andrews became aware of the investigation against him, he threatened to expose aspects of one of the women's private life to the media if she went to the police. Prosecutor Owen Edwards read an impact statement from one of Andrews' harassment victims. He said: 'Within the same context of talking about her own struggles, she has always struggled to understand how he could behave in the way he did but continue to hold a senior position in the police and not show signs at work. 'Even now she struggles to have faith and trust in the police and criminal justice system as a result. She believes he has an issue with women and he has certain sociopathic tendencies.' Reading the second victim's impact statement, he said: 'He was motivated by the need to control and bully as he asserted his power and influence over her. 'She has lost sleep and still finds it difficult to come to terms with it. She just wants to live her life in peace, free from harassment, bullying, threats and intimidation.' Disgraced: When Andrews (pictured) became aware of the investigation against him, he threatened to expose aspects of one of the women's private life to the media if she went to the police . Mr Edwards added: 'The most obvious aggravating feature is that throughout all of this the defendant was a senior police officer or senior manager employed by the police and circumstances in which he used that position to add to the distress and concern caused to both complainants by his acts of harassment and stalking. 'In both cases he was to imply and expressly state that they would never be believed and that he had the power to affect an investigation taking place and he had knowledge which allowed him to ensure that if any complaints were made they would never be believed.' His defence team said that being imprisoned would 'break him' following the convictions from offences committed between 2012 and last year. In an earlier plea for mercy at Manchester Crown Court, Andrews said his personal difficulties stemmed from his childhood in an orphanage which left him 'needy' and 'attention-seeking'. In mitigation, Tania Griffiths QC called a psychiatrist to give evidence following an assessment of Andrews. Dr John Frazer said: 'He was finding it hard because when he was in the police force in a senior position, he got a lot of emotional support and help and he lost that and that was bereavement for him. The lack of structure suddenly had an effect on him.' Mrs Griffiths added: 'Financially, this case has ruined him. This man has saved many lives. Not everyone can say that. 'Needy': In an earlier plea for mercy at Manchester Crown Court, Andrews (pictured) said his personal difficulties stemmed from his childhood in an orphanage . 'He has put his own life on the line in order to do that. He has tackled an armed gunman. He didn't need to do that. There are givers and takers in life and Mr Andrews is absolutely a giver.' Sentencing, Mrs Justice Francis Patterson said that because of the offences she had no choice but to send Andrews to prison. She said: 'You knew there was an investigation proceeding and these texts were clear attempts by you to exert control to stop her co-operation with the ongoing police investigation. 'You knew perfectly well from your great experience as a police officer what was happening and you were desperate to stop it. 'You acted deliberately in a manner to intimidate her - a manner that was as arrogant as it was ill-judged. 'You thought not only that you were above the law but you could manipulate the course of justice to your own ends. 'In your favour, from a difficult beginning where you were rejected by your father and your mother died and he took you to an orphanage you made a real success of yourself. 'You have risen through the ranks to the highest echelons of the police force and made valuable contributions to society. 'Before these events you were a man of outstanding good character. You were at a time of life when you should have been enjoying the fruits of your endeavours and all of those endeavours you, and you alone, have thrown away.'
