The BBC has released the trailer for the new series of its acclaimed Belfast-set police drama Blue Lights and has announced that season two will premiere on BBC One on Monday 15 April at 9pm.
The new season sees Siân Brooke (Grace Ellis), Martin McCann (Stevie Neil), Katherine Devlin (Annie Conlon), Nathan Braniff (Tommy Foster), Joanne Crawford (Helen McNally), Andi Osho (Sandra Cliff), and Hannah McClean (Jen Robinson) reprise their roles.

Also returning are Paddy Jenkins (Happy Kelly), Desmond Eastwood (Murray Canning), Andrea Irvine (Nicola Robinson), Aoibhéann McCann (Geraldine Gilroy), and Abigail McGibbon (Tina McIntyre).
Joining Blue Lights for season two are Frank Blake (The Border, Normal People) as new Constable Shane Bradley; Seamus O'Hara, who starred in the Academy Award-winning short film An Irish Goodbye, as Lee Thompson; and Seána Kerslake (Bad Sisters, Ballywalter) as his sister Mags.

Craig McGinlay (Cobra) plays "Lee's right-hand man Craig", and Dan Gordon (Bloodlands) plays Mags and Lee's Uncle Rab.
Casualty's Belfast-born star Derek Thompson will make his Blue Lights debut as retired police officer Robin Graham, a man whose "past and conscience catch up with him" when trainee solicitor Jen Robinson (Hannah McClean) investigates an old case.

Teeing up season two, the BBC said: "Grace, Annie, and Tommy are growing up fast as police officers, but nothing can prepare them for the turmoil they face every day. It's a year since the fall of the McIntyre crime gang and the vacuum has been filled by rival gangs, all competing for dominance.
"Constable Shane Bradley is drafted in to help, but his motivations are unclear. Tommy is dangerously seduced by the world of intelligence policing, while Grace struggles to deal with her son's absence, and growing feelings for fellow officer Stevie.

"As a young loyalist threatens to take over the city, the officers face a major gangland feud - culminating in a violent and devastating confrontation."
Writers and directors Declan Lawn and Adam Patterson added: "Blue Lights is a very personal project for us, set in the city where we live, so for us making this show is a special kind of privilege.

"In series two, we join our officers exactly a year after the events of series one, and now they're facing a whole new set of professional and personal challenges.
"We're very excited indeed about bringing you this next chapter of the Blue Lights story. Take a beat!"
