DI Costello showed a major sign of being corrupt in Coronation Street tonight (Friday, October 3), but he wouldn’t be the first police officer to.
The Weatherfield police force has showed many signs of corruption over the years, and it hasn’t always played by the books.
Here are the top moments Corrie police strayed away from the law.

1. Craig covering up Faye’s crime
In 2022, Craig Tinker found out that his girlfriend Faye had been involved in the death of an elderly man named Ted. Emma Brooker had been in the car with Faye when she’d knocked down Ted.
Ted later died of his injuries, with the women failing to hand themselves into the police.
Faye eventually confessed everything to Craig, and he agreed to forget about the whole thing.
However, the guilt ate away at home and he ended up stepping down from his role in the police force before going back to it later on.
2. Kit Green planting Lauren’s hair
When Lauren Bolton disappeared, Sarah Platt had been planning on planting one of Lauren’s hairs in Nathan Curtis’ van so he’d get arrested for the crime.
Kit caught Sarah, but desperate to solve a case, he ended up planting the hair in the van himself.

3. Kit deleting his car info in Joel case
When is was revealed that a red car had been involved in the disappearance of Joel Deering, Kit knew that things could be pinned on him as he’d had an encounter with Joel on the night he died.
To save his own skin, Kit deleted his car registration info from the system to avoid suspicion.
4. Becky Swain’s whole death
A more recent storyline of police corruption came when Becky Swain returned from the dead after almost four years.
She revealed that she was working undercover to bring down an OCG but had to fake her own death and move to Alicante to protect her family.
As part of this though, she’d actually stolen the identity of a homeless woman named Tia Wardley and had Lisa and Betsy believe that she’d died instead.

5. DI Costello doing anything to hide the truth
DI Costello not only was involved in Becky’s whole fake death plot, but he’s also been sure to pull some strings to make things go his way and keep his secrets hidden.
From allowing Lisa to go back to work, to paying someone to pretend to be Tia Wardley, we reckon there’s more to his corruption.
