Line of Duty fans cringe over Steve Arnott's awkward sex scene

Poor Steve Arnott left Line of Duty fans cringing tonight over his awkward sex scene with ex-girlfriend Sam Railston.

The DS was left paralysed after he was pushed down a flight of stairs by 'balaclava man' during the fourth series. And while he has been able to walk again, despite previous doubts, he has been left in pain.

This evening, Steve reconciled with ex Sam and the pair ran upstairs to enjoy a steamy bedroom session.

But Steve stopped in the middle of their romp and ended up crying in the toilet after suffering from erectile dysfunction following his accident.
