Sue Sim came to national prominence five years ago when she led the Northumbria Police manhunt for killer Raoul Moat . A chief constable facing a bullying probe for her alleged Alex Ferguson-style 'hair dryer treatment' of colleagues is to retire with full pension after 30 years of service. Sue Sim, who came to national prominence five years ago as Northumbria Police dealt with the Raoul Moat manhunt, said she was 'sad' to leave the force but was retiring to spend more time with her family. It was announced last month that Ms Sim was to be investigated by her Police and Crime Commissioner's office for alleged misconduct. Although she was not suspended after the accusations were made against her, it was reported those below her were walking on 'eggshells' such was the manner in which she delivered her assessments. Her style has been compared to her predecessor Sir John Stevens, who delivered what have been described as legendary 'b**********' to the officers under his command. A Northumbria Police spokesman today confirmed she will retire with full pension despite being the subject of an investigation. Ms Sim said: 'After careful consideration I have decided to retire when I reach my 30 years service on June 3. 'My family have made many sacrifices to enable me to have such a fantastic career and it is now time to spend more time with them. 'I am obviously sad to leave but it is the right time and I am confident I have left a legacy of high performance that will continue. 'I have been extremely fortunate to have had a marvellous career and I am as committed to serving the public as I was when I first joined Merseyside Police in 1985.' Chief Constable Sim came to public prominence during the hunt for crazed killer Raoul Moat in 2010 when she held her position in a temporary capacity. She described the search for Moat following the murder of Christopher Brown and shooting of one of her own officers, PC David Rathband, as 'one of the most challenging times' of her career. During this time she fronted public appeals to locate the killer and became the face of the police response, during which officers were warned they were targets. She said: 'That was one of the most challenging times of my career and the largest manhunt the country has seen for 44 years. 'I am immensely proud of my officers and staff who went about their roles fully aware of the threats against them, but determined to support the public.' Vera Baird, police and crime commissioner for Northumbria, said she would miss working with Ms Sim. Ms Baird said: 'Chief Constable Sue Sim gave me formal notice of her decision to retire on Wednesday April 8 and she will leave the force on June 3 when she has completed 30 years of public service in policing. 'Sue has brought passion and enthusiasm to her role with Northumbria Police, always remaining focused on cutting crime and ensuring victims of crime are at the heart of everything Northumbria Police does. 'She and I have worked well together over the two-and-a-half years since I became police and crime commissioner. PC David Rathband (left) was left blinded after being attacked by Raoul Moat (right) in July 2010. Chief Constable Sue Sim, who became the police face of the Moat manhunt, has now announced her retirement . 'She responded to the challenge of this new governance structure very positively and my experience of her is that she always, without exception, delivers what she has promised.' Ms Baird said Ms Sim had played a 'key role' in the success of the force. 'I will miss our joint working and I wish her well in her retirement,' she said. Last month, Ms Baird announced that she had appointed a judge to lead an inquiry into allegations that Ms Sim might have 'fallen short of her duty as a police officer to treat colleagues with respect and courtesy'. She said: 'Over the past few days, I have sought clarification about the issues raised by some officers. 'I am now clear that they wish to make complaints against the chief constable of Northumbria Police which merit investigation.' Ms Sim said she would co-operate with the inquiry.
