Met launches criminal probe on basis of Miranda data

The Metropolitan police have launched a criminal investigation sparked by "tens of thousands" of pages of data seized from David Miranda at Heathrow Airport, their lawyer Jonathan Laidlaw QC said.

The QC told the court that the police were only "partway through" examining the data.

That which has been inspected contains in the view of the police highly sensitive material, the disclosure of which would be gravely injurious to public safety and thus the police have now initiated a criminal investigation.

I am not proposing to say anything else which may alert potential defendants here or abroad to the nature and the ambit of the criminal investigation which has now begun.

There is an absolutely compelling reason to permit this investigation to continue.

– Jonathan Laidlaw QC
