According to The Guardian, a documentary producer, a photojournalist, a live-streamer and a freelance reporter have been charged with serious offences under Washington DC’s anti-rioting laws.

It comes after two more journalists, Evan Engel of Vocativ and Alex Rubinstein of RT America, were also caught up in the police action against demonstrators.

All have faced court and have been released to await further hearings in February and March. But none of the arrest reports make any specific allegations against them.

Jack Keller, a producer for the web documentary series ‘Story of America’, said he was charged and detained for around 36 hours, despite telling police he was covering the demonstrations as a journalist. His phone has yet to be returned to him.
