DCI Roy Slater is a minor character in the British sitcom Only Fools and Horses. He is played by Jim Broadbent.
Slater was an old school mate of Del Boy's. He was renowned for his slyness. After a gang of lads pinned Slater down, Trigger tried to pour itching powder into his belly button. Del rescued Slater, but Slater later told the headmaster that Del was seeing his sister behind the bikesheds. When they played Pirates, he was always the one who walked the plank. He longed to play Bluebeard but was so snidey that the others didn't let him. They eventually let him be Bluebeard, but to Slater's horror, Bluebeard had to walk the plank.
Slater never played fair when he became a police officer. He arrested his own father for having a faulty light on his bike while going to the chip shop. He arrested Del and the family for stealing a microwave. Del managed to trick Slater into signing a form that granted Del immunity from prosecution if he grassed the man up. It turned out that the 'phantom of the market' was Del Boy. He also set Del up for smuggling diamonds but he ended up being sent to prison for five years.
