In the past he's provided the narration for Traffic Cops, the Beeb's docusoap following various police teams across the country as they attempt to crack down on car crime. Previous series have focused on the activities of those working in South Yorkshire - as does this new airborne spin-off.
Theakston is the man behind the microphone once again as cameras chart a day in the life of the county's helicopter.
It's been brought in to help catch the scores of thieves, drunks and disqualified drivers who take to the roads every day, often leading police pursuit vehicles on a dangerous chase.
The chopper has proved hugely useful so far - it has a 95 per cent success rate - although at a price of pounds 4million, it's also very expensive.
In the first edition of the new series there's a chance to see the vehicle in action, utilising many of its technological advancements - including heat-seeking, thermal-imaging cameras and a powerful searchlight - in an attempt to keep villains off the roads.
TURN BACK TIME (BBC2, 10pm).
IN the last of this entertaining series, Dara O'Briain asks comedian Phill Jupitus what he would do differently if he could live his life again.
It turns out there are a few things the Never Mind the Buzzcocks regular would like to change - starting with his education.

The stand-up also talks about a few of his suspect career choices, including the time he agreed to perform with the Who at the Royal Albert Hall, little suspecting he would be filling in for the band half-way through their set. Apparently, he received such a bad reception, Roger Daltrey had to help him off stage.
It turns out Phill's final regret is not doing enough exercise. This at least helps to explain why he was so keen to appear on Turn Back Time, as he admits that many of the programmes he's invited to take part in are about the war on obesity.
