CCTV footage has been released showing officers inside a police station under attack during a riot in Bristol.
A total of 42 people have been arrested, with a 14-year-old boy also attending a voluntary interview, in connection with the incident which followed a peaceful Kill the Bill protest in the city.
The riot, on March 21, saw around 500 people march on Bridewell police station, set fire to police vehicles and attack the station.
Avon and Somerset Police said on Tuesday that 44 officers were assaulted during the incident, with 39 sustaining injuries as a result.
One other officer was also injured but not from an assault, a spokesman said.
The force previously corrected a statement it issued the day after the riot, which wrongly claimed officers had suffered broken bones and one had sustained a punctured lung in the disorder.
Detective Chief Superintendent Carolyn Belafonte said: "It's now four weeks since the shameful scenes outside one of our neighbourhood police stations.
"Thousands of hours of digital media including CCTV and mobile phone footage have been viewed and significant progress has already been made."
