Those who follow the  soap are keen to find out more about the character, played by Daon Broni, who is the head of CID within Weatherfield Police.

He has appeared intermittently since August 2024 but its in more recent months that Costello has been causing problems for fan-favourite DS Lisa Swain, despite him claiming he’s only been protecting her.

Fans will recall that Costello pushed Lisa into having therapy sessions, after the death of her colleague PC Craig Tinker triggered memories of the loss of her own wife, Becky Swain, in the line of duty.

Fans first heard about Becky last year when Lisa opened up to Carla Connor about her late wife as the pressures of being a detective sergeant on the Lauren  and Joel Deering case and being a mum to teenage daughter, Betsy, got on top of her.

Since then, Corrie viewers have watched Lisa and Carla fall for one another and after moving into their first home together, No.6 Coronation Street, earlier this year, the pair recently got engaged.

But in a shock twist last month, Becky arrived in Weatherfield – alive and well. Lisa’s jaw was on the floor to see Becky, alive and well, opposite her in her new home with new fiancée Carla, with the arrival coming on their daughter Betsy’s, 18th birthday.

As an emotional Lisa was unable to figure out if what was happening was real, Becky explained that she had been in Spain under another name having been put into witness protection, following an undercover operation gone wrong.

Since then, Lisa has clearly been battling with her feelings, while also trying to get to the truth of what really happened. She confronted her boss, who claimed Becky’s story to be true, but Corrie fans think he’s hiding more than he’s letting on, with DC Kit Green the only one suspicious of his superior.

In the meantime, actor Daon has took to Instagram with a snap of himself, Vicky Myers and Jacob Roberts, who play Lisa and Kit, on Instagram as they appeared in the soap’s iconic Rovers Return.
