Coronation Street Bombshell: DI Costello’s Deal with Kit Green Exposes Weatherfield’s Deepest Police Betrayals
Corruption Creeps Through the Cobbles
Coronation Street dropped a shocking twist on Friday (October 3) as DI Costello showed signs of corruption — and possibly made a deal with Kit Green that could unravel everything. But as longtime fans know, the Weatherfield police force has a long and messy history of bending the rules.
From cover-ups to faked deaths, this isn’t the first time law and order in Coronation Street has blurred into betrayal. Here’s a look back at the most jaw-dropping police scandals to ever rock the cobbles.
1. Craig Tinker Covered Up Faye’s Crime
In 2022, Craig Tinker found himself torn between love and duty when he learned his girlfriend Faye Windass had accidentally killed elderly pedestrian Ted while driving with Emma Brooker.
Instead of turning her in, Craig chose silence — a decision that would haunt him. The guilt grew unbearable, forcing him to temporarily step down from the force before later returning to duty. It was one of Corrie’s earliest signs that even the good cops weren’t immune to compromise.
2. Kit Green Planted Evidence in Lauren’s Case
When Lauren Bolton vanished, Sarah Platt planned to plant a strand of Lauren’s hair in Nathan Curtis’ van — a desperate move to see him arrested.
Kit caught her in the act but, in a shocking twist, did it himself to fast-track the investigation. The decision spiraled into chaos, showing just how far Kit was willing to go to protect his reputation — and the case.
3. Kit Deleted His Car Data After Joel’s Disappearance
After Joel Deering went missing, CCTV revealed that a red car had been seen near the scene. Knowing he’d crossed paths with Joel that same night, Kit panicked.
He deleted his car registration data from police records — a desperate bid to erase any link between himself and the investigation. With every action, Kit slid deeper into corruption’s shadow.
4. Becky Swain’s “Death” and Secret Life
The shocking resurrection of Becky Swain remains one of the wildest Coronation Street police twists in recent memory.
Believed to have died in the line of duty four years ago, Becky resurfaced with an unbelievable story — she’d faked her death while working undercover to infiltrate an organised crime group. To protect her family, she stole the identity of a deceased woman, Tia Wardley, and vanished to Alicante.
Her return shattered Lisa Swain’s world — and exposed just how deeply the police were willing to deceive to keep secrets buried.
5. DI Costello Pulling Strings and Paying Off Witnesses
Fast forward to now, and it’s DI Costello who has become Weatherfield’s latest suspect in corruption.
From covering up Becky’s fake death to allegedly paying someone to impersonate Tia Wardley, Costello has proven he’ll go to dangerous lengths to protect himself — and others.
Recent scenes suggest his dealings with Kit Green could expose both men, with Costello manipulating events behind the scenes to keep his career — and his secrets — intact.
As whispers of betrayal grow louder, Costello may soon find himself caught in the very web he’s spun.
6. Neil Clifton’s Horrific Betrayal of Power
Perhaps the most disturbing case in Corrie’s police history belongs to Neil Clifton, a supposedly trusted officer who was revealed to be part of Nathan Curtis’ sex trafficking ring.
Neil preyed on Bethany Platt, abusing his authority and his position. His arrest and 2017 conviction remain one of the soap’s darkest storylines — a grim reminder of just how deep corruption can run.
The Shadow Over Weatherfield’s Finest
From misplaced loyalties to calculated deception, the badge has often meant little in Weatherfield. And now, with DI Costello’s alliance with Kit Green threatening to explode, Coronation Street looks set to deliver one of its biggest betrayals yet.
For a town that thrives on secrets, this latest twist might finally push Weatherfield’s police beyond redemption.
