A 'Critical Mass' protester who was arrested after yesterday's demonstrations told ITV News he was unable to make a phone call until 10am this morning because the police station he was in was 'too busy'.
He said around 150 people in total were first kettled, then arrested, put on three buses and taken to Charing Cross police station at 11:45pm.
It wasn't until 2am that they were taken inside the police station.
The protester's account suggests he was not allowed a phone call for about 11 hours after his arrest.
All protesters were bailed this morning without charge, he said.
