No Offence

No Offence is a British television police procedural drama on Channel 4, created by Paul Abbott. It follows a team of detectives from Friday Street police station, a division of the Manchester Metropolitan Police (a fictional version of the Greater Manchester Police). The series stars Joanna Scanlan as the protagonist, Detective Inspector Viv Deering. The first series focuses on the team's investigation into the serial murders of young girls with Down syndrome. It was renewed for two further runs. The second series of seven episodes began broadcasting on 4 January 2017, and follows the investigation into Manchester crime boss Nora Attah (Rakie Ayola). It was filmed on location in Manchester.

In the UK, the first episode of No Offence launched with 2.5 million viewers, Channel 4's biggest midweek drama launch for more than three years. Although subsequent episodes lost overnight viewers, dropping as low as 1.2 million, the weekly consolidated series average remained at 2.5 million and finished 47% up on Channel 4's slot average. In France, the first episode of No Offence aired on 29 February 2016 on France 2 and was watched by 5.46 million viewers, 20.4% of the TV audience. The next three episodes were shown back-to-back that evening and together achieved an average 4.6 million viewers, 19.3% of the TV audience.

A third series was confirmed in July 2017. Filming took place in Manchester in March 2018 and it began broadcasting on 13 September 2018. The six-episode series has a political focus, with the main storyline following the attempted murder of a local politician by a far right group. On 19 October 2018, Paul Abbott stated in an interview that he had begun working on ideas for a potential fourth series, but on 28 November 2019, Executive Producer Martin Carr confirmed on Twitter that the show would not be returning.

Plot
In the first series, DI Viv Deering is introduced as the dynamic but blunt leader of a team of detectives at a fictional police station within the 'Manchester Metropolitan Police'. DC Dinah Kowalska misses out on promotion to DS after leaving the scene after an impetuous foot chase results in a death. She then uncovers a link between a murder, a drowning and a disappearance: someone is killing girls with Down syndrome. While negotiating different cases, the team must solve the case as more girls come into danger. The prime suspect is killed whilst fleeing arrest, but Dinah and Viv separately conclude that Viv's husband is also involved. Viv burns the evidence and plans to kill rather than arrest him, but he is killed by Cathy while she and Dinah are holding him at Viv's home. With Viv they cover up their involvement before the body is found.

The second series begins a little over a year later, as Viv returns after extended leave and attends a gang funeral, which is bombed despite the police presence.

Main

 * Detective Inspector Vivenne Deering (Joanna Scanlan) is a cast-iron cop with a tough-love approach to managing her team. She is at the prime of her life and capable in her job. However, with a high-flying career comes a disintegrating home life.
 * Detective Constable / Detective Sergeant Dinah Kowalska (Elaine Cassidy) is a strong yet impulsive member of the team. She is passed over for a promotion to sergeant following a stupid mistake, and it's not long before she makes another move in following her emotions, which threatens her job. She lives with her eccentric Polish mother Magda and her teenage daughter Tessa.
 * Detective Sergeant Joy Freers (Alexandra Roach) is an equally brilliant detective but one who is shy of the spotlight. Her promotion to sergeant ahead of Dinah removes her from her comfort zone; if only she recognised her own brilliance behind her anxiety.
 * Detective Constable Spike Tanner (Will Mellor) is a risk-taking headstrong man amongst the powerful women of the group. He provides emotional glue for the group, but he is also a cheeky fun-loving guy.
 * Randolph Miller (Paul Ritter) is an eccentric in forensics, despite the team's general despair of his lacklustre attitude to the job. Often hungover, it's lucky Randolph's a maverick who's amazing at his job.

 * PC Tegan Thompson (Saira Choudhry) is a tough and ambitious officer. She refuses to suffer fools and has a good relationship with her police partner Stuart; is there a hint of romance?
 * PC Stuart O'Connell (Tom Varey) is a smart and switched-on policeman, and Tegan's partner. He aims to make sergeant, but he cannot get drawn into the trouble his colleagues like to indulge in.
 * PC Jonah Mitchell (Ste Johnson) is overweight and mischievous, yet enthusiastic; he is Taz's partner.
 * PC Taz Ahmed (Neet Mohan) is a happy-go-lucky yet calming influence on the team, and Jonah's partner.
