The spy drama stars Richard Armitage and Hermione Norris
A prop used in the TV spy drama Spooks sparked an alert near a south-east London station which disrupted train services for more than an hour.
A passer-by spotted the item, described as an oil drum with wires protruding from it, in a yard close to Deptford train station on 1 July.
The production company Kudos Film and Television said the item was "stored securely" in a private yard.
Southeastern train company said services were suspended until midnight.
The drama, which revolves around MI5, is shot at a studio in Bermondsey.
A spokeswoman for the production firm said: "A prop used on Spooks was stored securely in the production's private courtyard.
"A member of the public looked into the yard and, on seeing the prop, decided to alert the emergency services as a precaution.
"As soon as the Spooks production team were contacted, they confirmed the package was just a prop and not dangerous."
A spokesman for the train company said the alert delayed about a dozen trains travelling between Charing Cross and Dartford, Dover and Hastings.
Some trains were stopped on the tracks while others were delayed for up to 40 minutes at the station.
