Andi Osho, whom you may recognise as Arabella's therapist in I May Destroy You, is joining the cast for Line of Duty series six. Osho plays TV reporter Gail Vella, who is fatally shot outside of her house in the period of time before series 6 begins. It's Vella's murder that DCI Joanne Davidson and her team (which now includes DI Flemming) are trying to solve.
