The peaceful protests against the new UK law that gives more power to the police to restrict the street protests turned violent injuring two police officers.
Police said that the protests were initially peaceful and were later turned violet following a"distortion" by a small minority.
Home Secretary Priti Patel said that the scenes at Bristol were unacceptable. "Our police officers put themselves in harm's way to protect us all. My thoughts this evening are with those police officers injured," he said.
"All those involved in this criminal behavior will be identified and brought to justice. There will be significant consequences for behavior such as this," Avon and Somerset's chief superintendent, Will White, said in a statement.
The protesters were protesting against the new Police, Crime, Sentencing and Courts Bill, which will give new powers to the police to restrict the protesters. The bill will allow police to set the time limits and noise limits on the street protests.
Thge activists on the streets were carrying placards with slogans such as "Kill the Bill", "The Day Democracy Became Dictatorship" and "We Can't Be Silenced That Easy".
The heavy-handed police response to a London vigil for murder victim Sarah Everard on March 13 has caused widespread outrage and criticism against the police in the UK.
