Richard Madeley has reported to the police two "peeping Toms" who were allegedly flying a drone over his garden to spy on him.
The former This Morning host tweeted that he gave chase to the "creeps", locating the suspected owners in a nearby white van, before contacting his local police force in Looe, Cornwall.
He posted: "So who are the two peeping toms who just flew a drone over my garden near Looe? Chased them down to a white van ... Drove off when challenged."
He continued: "Police being informed. What creeps."
Madeley gave the licence plate number of the two alleged perpetrators out on Twitter in a hope for information.
Famous couple Madeley and his wife Judy Finnigan have owned a property in Talland Bay, near Polperro, since 1998, according to an interview with the Plymouth Herald.
Drones with attached cameras have long sparked privacy fears among celebrities, including Kanye West, who has accused paparazzi of "stalking" his daughter with the gadget.
The Devon and Cornwall police have been contacted for comment.
