Line of duty series#

Throughout the series, AC-12 investigate seemingly disparate cases involving seemingly corrupt police officers, with each series focusing on a different corrupt officer. They work under the supervision of Superintendent Edward 'Ted' Hastings ( Adrian Dunbar), who is one of several Senior Investigating Officers responsible for uncovering corruption within the police force. Arnott is partnered with Detective Constable Kathrine 'Kate' Fleming ( Vicky McClure), a highly commended undercover officer with a keen investigative instinct. In the subsequent investigation, Arnott refused to cover up negligence in the planning and execution of the raid and unable to work in his unit anymore, Arnott receives a transfer to AC-12, a unit tasked with uncovering police corruption. Line of Duty follows Detective Seargent Steven 'Steve' Arnott ( Martin Compston), a former authorized firearms officer who led an operation to catch an Islamic terrorist intending to detonate a bomb, but the strike team mistakenly entered the wrong apartment and shot dead an unarmed innocent man. Throughout the series, AC-12 investigate seemingly disparate cases involving seemingly corrupt police officers, with each series focusing on a different corrupt officer and AC-12 soon realize the pervasive nature of corruption and the police's deep-rooted links to an organized crime group with ties to drug running, prostitution, child exploitation and people trafficking. Arnott is partnered with Detective Constable Kathrine 'Kate' Fleming ( Vicky McClure)), a highly commended undercover officer with a keen investigative instinct. It looks as though Carmichael is still heading up the merged unit, and close colleagues to the Chief Constable have been promoted to senior positions.Ĭould this mean that there's still more to discover about Osborne and his motivations? We do know that he worked closely with Buckells at one stage, and that he had direct links to investigations that were connected to AC-12's enquiries.Line of Duty follows Detective Seargent Steven 'Steve' Arnott ( Martin Compston), a former authorized firearms officer who led an operation to catch an Islamic terrorist intending to detonate a bomb, but the strike team mistakenly entered the wrong apartment and shot dead an unarmed innocent man. The scaling back of anti-corruption units, and the suppression of AC-12's power, has continued despite the team's success in solving both the Gail Vella murder and in closing the longstanding OCG investigation (which was never officially recognised by those higher in the chain of command). It does still seem peculiar that the Chief Constable was so hell bent on shutting down AC-12's work, and that he carried out his vendetta of limiting resources to those areas of policing. While AC-12 suspected that he could have been involved in the clandestine network of corrupt officers, even at one point believing him to have possibly been The Fourth Man, he was never named as part of their investigations.

We know from his final press conference that Osborne is still continuing to downplay any links between the police force and criminal groups aside from a 'few bad apples.'
