When does Blue Lights start?

Series four of Blue Lights will officially begin at 9pm on Tuesday 29th September.

Episodes will air every Tuesday night on BBC One, but if you prefer to binge, all episodes will be available to watch from 6am on BBC iPlayer.

The news was officially announced on 16th September, as bosses shared new artwork of the cast.

It was back in August when bosses released the full length trailer for series four, showing Constables Grace Ellis, Tommy Foster, and Annie Conlon three years into their jobs as response officers, while facing a threat on the streets 'that the police can barely control'.

The BBC say of the plot for series four: 'Three years into their jobs as response officers, Constables Grace Ellis, Tommy Foster, and Annie Conlon are operating at their limit, facing a new threat on the streets that the police can barely control.

'Meanwhile the murder trial of Gerry Cliff exposes a dangerous and long-buried secret that leads to chaos both inside the police, and across the criminal underworld. As they grapple with big decisions about their future, Grace, Tommy and Annie must find the courage to face the greatest threat they have ever encountered: the truth'.

Series four will also see the return of actor Richard Dormer as Gerry Cliff, as well as Siân Brooke as Grace Ellis, Martin McCann as Stevie Neil, Katherine Devlin as Annie Conlon and Nathan Braniff as Tommy Foster.

Whilst we await the fourth instalment, series one to three of Blue Lights is available to watch on BBC iPlayer now.
