Television film of the Michael Stone incident at Stormont must be handed over to the police, a judge has ruled.
The Police Service of Northern Ireland applied for an order at Belfast Recorder's Court on Tuesday compelling the BBC, UTV and RTE to hand over film.
A police officer said he also wanted footage in a BBC camera left running after it was abandoned in Parliament Buildings last Friday.
The judge granted the order which was sought under the Terrorism Act.
Judge Tom Burgess said he was satisfied that various film clips would be of value in the public interest. He said the order included the film in the abandoned camera which was recovered by bomb disposal experts as they checked out the building.
It was put in a sealed bag and handed over to police but has not been seen by anyone.
