Police arrested two more people after rioting broke out in Bristol on Sunday during a protest against “Kill the Bill”.
It comes after 14 more arrests – including one related to the weekend rampage – were made during another protest in the city.
At lunchtime, a spokesman for Avon and Somerset Police Department said: “Officials and staff are making significant progress as they continue investigating violent incidents that broke out in Bristol city center on Sunday.
“Two other people, a 20-year-old man and a man who is currently refusing to provide details, have been arrested on suspicion of violent disturbance and are in custody, bringing the total to nine.
“In addition, we are currently investigating attacks on 40 officers and one member of the media. Fortunately, after a full medical examination of the two hospitalized officers, no confirmed broken bone was found.
“Since we started a special form for members of the public to provide footage or provide us with information on who was involved, we’ve received 210 submissions and an additional 68 calls in our control room.
Ch Supt Carolyn Belafonte, who appealed on the BBC’s Crimewatch Roadshow this morning, said, “As we said from the start, this will be an extensive investigation that has the potential to be one of the largest in our history.
“The fact that we are investigating 40 attacks on officials and one member of the media as a result of an incident shows the extent of the wanton disturbance that took place that night.
“We are convinced that by carefully examining digital footage worth more than two terabytes, we will make clear progress in identifying those responsible and assume that more images will soon be published in the online gallery we have set up.
“One of the people we believe we have already identified is a suspect in the fire that destroyed a community mobile police station.
“We would like to thank every member of the public who contacted us to provide footage and information or to pass on their good wishes and kind thoughts.”
