The trial of student protesters Alfie Meadows and Zak King began on Monday of last week.
It is the third time a jury has been sworn in to hear the case. The first trial ended in a hung jury and the second was abandoned after a series of delays.
In the first days, two police constables took the stand to describe their experiences on the protest on 9 December 2010.
That day Alfie and Zak were separately near Parliament Square as police contained protesters.
PC Bartlet, a foot officer on the day described his experiences of the day. “I was facing Parliament Square so I had no idea what was happening behind me,” he said.
“The sergeant told us to break the cordon and form against the wall. We didn’t know what to do. The atmosphere was highly charged and people were excited.
“They were shouting ‘who’s kettled now’ and ‘if you throw down your weapons you can leave peacefully’.
The police bronze Commander Woods, also took the stand.
Alfie and Zak were arrested after taking part in the movement against the tripling of tuition fees by the coalition government.
The trial runs every day at Woolwich Crown Court.
The Defend the Right to Protest campaign is calling on people to fill the public gallery and show their support during the trial.
Proceedings Monday to Friday from 10am, 2 Belmarsh Rd, London SE28 0EY www.defendtherighttoprotest.org
