Met PC Grant Long, 34, was caught in a sting operation after expressing sexual interest in children and attempting to groom a supposed 10-year-old girl, leading to his arrest and dismissal from the force.
He pleaded guilty to encouraging or assisting in the sexual assault of a child and distributing indecent images, receiving a two-year suspended prison sentence.
A senior officer has condemned his actions as a grave abuse of trust that undermines public confidence in policing.
