Police say over 130 protesters were arrested last night and taken to various stations across London.
It did take a while to process them, police said, and agreed with the protester we spoke to who said the ones who arrived at Charing Cross at midnight were brought into station at around 2am.
And police say they are looking into the claim that they were denied a phone call until 10am, but denied they were deliberately slow to stop people attending today.
