Martin Compston was seen shopping in London just days away from the Line of Duty series finale.
The actor, who plays DI Steve Arnott in the show, was photographed with a JD Sports shopping bag in the capital on Tuesday.
He didn't give anything away about what's going to happen in the hotly-anticipated final episode, so we're no closer to discovering who the mysterious H is.
Martin, 36, was dressed in a tight, grey long-sleeved top, which he teamed with a pair of baggy black jeans and a pair of matching trainers.
The TV star donned a grey baseball cap and sported his trademark beard.
Martin was seen playing on his phone as he strolled around London.
He carried a big shopping bag from the sportswear store.
While he seemed to be trying to keep a low-profile, Martin stopped to chat to a fan who approached him.
He posed for a selfie with the fan on his outing.
Martin, who was born and raised in Greenock, Scotland, has spent the majority of the last year and the numerous lockdowns in Las Vegas, with his wife Tianna Chanel Flynn.
The couple live in a £300,000 mansion in an exclusive gated community with their baby son and their pet pitbull.
He met Tianna on a night out in Los Angeles where she was working as a nightclub manager at Hudson Hotel.
They married in a stunning ceremony at Mar Hall, Renfrewshire.
Martin travels to Belfast for four months at a time when he is filming Line of Duty.
This Sunday will see the final episode of the sixth series of Line of Duty.
AC-12 are getting closer and closer to discovering the identity of H, the bent copper who is working within organised crime.
The BBC has released a trailer for the upcoming episode.
The footage starts with a montage of suspicious happenings over the series, from the trashed prison van to the Spanish siege and Gail Vella's murder, while Ted's voice can be heard.
"All these suspicious deaths were orchestrated by one officer in particular," he says.
DCI Joanne Davidson, AC-12's latest target, is seen being led out in handcuffs, while a copy of a transcript is seen with the word "definate" highlighted.
"H," Ted continues. "The fourth man."
A worried Jo is seen being transported in a vehicle as she asks what is going on, but the smirking prison guard doesn't answer.
A police car chase ensues and members of AC-12 walk out wearing bulletproof vests and holding guns as Ted tells them about what they are about to do.
As the team appear to intercept a vehicle, Steve screams at them to "get down" while holding a gun.
Kate also jumps out of a van holding a gun as she shouts: "Armed police!"
*Line of Duty returns on Sunday at 9pm on BBC One
