Way before Alec Hardy came to life, David Tennant was known for playing another police officer in another ITV series, Duck Patrol.

Originally airing in the UK in 1998, a comedy drama from the creators of 'Second Thoughts' and 'Faith In The Future', Duck Patrol deals with the activities of the officers of the Ravensbeck River Police Station, whose job it is to maintain law and order along the river's banks.
The  Sarge is supposed to be in charge of the station, but he tends to concentrate on his fishing and leave the day-to-day running of everything to Prof (Richard Wilson "One Foot In The Grave")
Other main characters include Prof's girlfriend, Val (Sue Johnson "The Royle Family"), love struck young copper Darwin, (David Tennant), and the object of his affections, Marilyn (Samantha Beckinsale, "London's Burning").

We've recently raided our film collection and are uploading episodes of the series for you.
Today we publish episode 3.

Check out the episode Occurences below:
About Occurences:
Prof has cause to inform the owners of houseboat 'Sorrento' that they are inadequately moored but the other patrol members feel there is something suspicious about the owners. When Prof gets a tip-off from another owner that they are smugglers he and the team organize a raid, having brought a TV crew to film their success but as Prof has himself forgotten to moor the police launch it is Hero who gets the recognition when he dives in to retrieve the boat. The smugglers turn out to be dealing in cheap alcohol which they supply to local inns. Val is not entirely pleased with the result.
