Police have praised those who took part in the global climate strike protest in Brighton on Friday (September 20) and thanked everyone for their patience while it moved through the city.
Chief Superintendent Jane Derrick said: "We estimate that between 5-7,000 people joined the protest. The majority were youngsters, many of whom had probably not taken part in anything similar before, but they made our job of keeping everyone safe a simple one.
"There was some disruption as the protest moved from Hove Lawns to The Level, but as it passed smoothly through we were able to open up roads again behind it and everything was fully open again soon after 1.30pm.
"I'd like to say a big thank you to the participants and organisers and also those who weren't involved in the protest, but who may have been held up for a while, for their patience and support."
