"An undercover police officer 'chased himself round the streets' for 20 minutes after a CCTV operator mistook him for suspect. As the probationary officer from Sussex Police searched for suspects, the camera operator radioed that he had seen someone 'acting suspiciously' in the area. But he failed to realise that it was actually the plain-clothed officer he was watching on the screen, according to details leaked to an industry magazine. The operator directed the officer, who was on foot patrol, as he followed the 'suspect' on camera last month, telling his colleague on the ground that he was 'hot on his heels'."
