The Moment of Proof

Episode 14 (3x14)

:

A car hidden deep within a scrapper's yard unlocks the riddle of a suspected gangland shooting at a secluded location. As police build their case against their prime suspect, they can't place him at the precise location of the shooting at the time of the murder. Also today, police secure the UK's first conviction for modern day slavery at a car wash after the owner's phone is shown to have tracked the victims' minibus as they were brought into the country.
