5. Episode 5

The firearms squad responds to reports of a gang armed with machetes trying to break into a house and one officer ends up on the roof as the officers try to locate the suspects. On the roads, the pursuit of a stolen motorbike reaches an unsatisfactory conclusion when the rider nips down an alleyway to freedom, but when Callum uses a tracker to locate a second stolen bike, it's parked right next to the one that got away.
