The Federal Bureau of Investigation is offering a reward for information leading to the arrest of a suspect accused of injuring an officer by throwing rocks at law enforcement vehicles amid protests in Southern California on Saturday.

Rep. Nanette Barragán, who represents the area in Congress, said ICE was now bringing “their terror tactics and masked agents” to Paramount.

Trump said the federal government would "step in and solve the problem", after the Californian city saw a second day of clashes on Saturday between protesters and federal agents. Tear gas was used to disperse crowds as residents of the predominantly Latino Paramount district clashed with Immigration and Customs Enforcement (ICE) agents earlier in the day.
