Casualty's Rash Masum left his colleagues devastated after "struggling" for several weeks. The emergency department doctor has been struggling with the unexpected death of his dad Ashok has been left tortured following a relentless campaign by his boss, Patrick Onley. In recent weeks, Onley has targetted Rash, believing that he is the notorious whistleblower who gave footage of the run-down department to a TV company.

Despite Rash's best efforts to persuade Patrick that he isn't, the latest episode of the BBC medical drama opened up about the effects Patrick's bullying has had on him since the TV show aired, exposing the department. In one scene, Rash (Neet Mohan) confronted Patrick (Jamie Glover) in his office, saying: "You were right, I told them everything, I'm the whistleblower." A relieved Patrick responded: "Finally, it's not just me you lied to, it's them, what are they going to say? You made them look incompetent, how do you think they're going to feel? Having to work with someone who treated them like that.

" In the exposé, staff at the department were seen attempting to care for patients while being completely overrun. But Rash later hands his notice in and faces a brutal response from Onley. As he prepares to carry out his final task, he was humiliated by his soon-to-be former boss, who said: "Dr Massam, I thought we agreed effective immediately?" But as Rash attempted to continue, Patrick instructs security to remove him from the premises, leaving his colleagues .
