Los Angeles police said they made "mass arrests" after a fifth day of protests over the Trump administration's immigration action.
Los Angeles police say they have made mass arrests after a fifth day of protests over US President Donald Trump's immigration raids.
Mayor Karen Bassa declared an overnight curfew within a relatively small area of the city's downtown district, saying businesses were being vandalised and looted.
An uneasy calm has descended over Los Angeles after the first night of a curfew lifted on Wednesday, as cities across the US brace for more protests.
In Los Angeles, nearly 400 people have so far been arrested, including 330 undocumented migrants and 157 people arrested for assault and obstruction, including one for the attempted murder of a police officer.
Federal prosecutors have so far charged two men for throwing Molotov cocktails at police officers in two separate incidents.
A total of 4,000 National Guard troops and 700 Marines have been deployed to help quell the unrest.
Speaking alongside 30 regional mayors at a news conference on Wednesday, LA Mayor Karen Bass blamed the protests on US President Donald Trump's immigration raids, which she said "provoked" residents by causing "fear" and "panic".
"A week ago, everything was peaceful," she said. "Things began to be difficult on Friday when raids took place."
Bass suggested Los Angeles was "part of a national experiment to determine how far the federal government can go in taking over power from a local government, from a local jurisdiction".
She has previously called on the administration to end the raids.
Overnight, Los Angeles police said they made "mass arrests" after a fifth day of protests over the immigration action.
Trump's row with state officials ramped up after he deployed troops to LA.
The president has now vowed to "liberate" the city, but has been accused by California Governor Gavin Newsom of an "assault" on democracy.
