A police officer seen speeding with his blue lights and sirens on was picking up his mates from a night out.
PC Robert Potts, 43, made other cars pull over and went through a red light in his police car while driving from Uckfield to Eastbourne.
PC Potts then collected his three friends from their night out while he and his colleague were in the middle of their shift.
Chief Superintendent Steve Rayland, Head of Professional Standards Department, said: “The actions of this officer in this case fell far short of the standards we expect.
“We expect our officers to act with the utmost integrity, and in accordance with the Code of Ethics and the Standards of Professional Behaviour.”
PC Potts was found to have been driving illegally for no police purpose, which amounted to gross misconduct.
Following his behaviour in July last year, PC Potts was given a final written warning lasting three years for his gross misconduct.
