A video has been posted online that appears to show activists from the We Are Anonymous group drinking their own urine in protest at GCHQ.
The police refused to accept a potty full of urine on behalf of GCHQ so activists ceremoniously drank it.
People taking part in the four-day-long peaceful protest were warned by the long arm of the law that they were not allowed to take snaps of GCHQ spies as they popped inside for a meeting with Moneypenny and M.
Activists who are angry at reports that GCHQ and its American sister agency NSA have developed large programmes of mass surveillance of phone and internet traffic, organised the protest over the weekend.
Gloucestershire Police told protesters that there was a small matter of legality standing in the way of them snapping pictures of staff based at Cheltenham.
Other than the potty protest, the rest of the weekend was a bit of a damp squib. The protest got off to a slow start yesterday with confusion over when the protests would take place and only a handful of people turned up.
