An "obsessed" cop was jailed for using Crimestoppers to try to frame a former girlfriend for murder and drug dealing.
PC Abubakar Masum, 24, wrongly accused Tesco supermarket worker Mia Pitman of being involved with the criminal underworld.
Masum's calls led to armed police raiding her home looking for a Glock handgun and questioning her about a planned murder. A court heard the police officer developed an "obsession" with blonde Mia, 23, who was studying criminology at Swansea University.
