Family of slain officer frustrated as case dropped
The family of murdered police officer Yvonne Fletcher have said they are "deeply disappointed and frustrated" a suspect will not be prosecuted after key evidence was withheld for national security reasons.
The Libyan national, who is in his 50s, has been told the investigation against him will not proceed "at this time", the Metropolitan Police said.
PC Fletcher was killed as she policed a demonstration against Colonel Muammar Gaddafi outside the Libyan People's Bureau in St James's Square on April 17 1984.
The shooting sparked a 10-day siege of the building before 30 of the occupants were deported back to Libya.
