PSNI detectives investigating the murder of journalist Lyra McKee have searched the offices of a television production company in Paris.
The raid was led by two French Judges, with the assistance of French police.
Lyra McKee was gunned down in April 2019 while observing a New IRA riot in Derry’s Creggan estate.
The violence was orchestrated while an MTV documentary crew was making a film about dissident republicanism.
The footage they recorded has been handed to police. Detectives believe that a camera crew from the production company in Paris was in Londonderry throughout the week of Lyra's murder.
A European Investigation Order was carefully considered, sought and granted by Belfast Crown Court and the search was later approved and supported by senior members of the French judiciary.
A number of items have been recovered for further examination.
