Authorities say about 200 immigrants arrested in raids on 2 Southern California farms

Four U.S. citizens were arrested for "assaulting or resisting officers," the department said. Authorities were offering a $50,000 reward for information leading to the arrest of one person suspected of firing a gun at federal agents. At least one worker was hospitalized with grave injuries.

During the raid, crowds of people gathered outside Glass House Farms at the Camarillo location to demand information about their relatives and protest immigration enforcement. A chaotic scene emerged outside the farm that grows tomatoes, cucumbers and cannabis as authorities clad in helmets and uniforms faced off with the demonstrators. Acrid green and white billowing smoke then forced community members to retreat.

Glass House, a licensed California cannabis grower, said in a statement that immigration agents had valid warrants. The company said workers were detained and it is helping provide them with legal representation.

"Glass House has never knowingly violated applicable hiring practices and does not and has never employed minors," the statement said.

It's legal to grow and sell cannabis in California with proper licensing. State records show the company has multiple active licenses to cultivate cannabis.

Worker hospitalized after fall

On Friday, about two dozen people waited outside the Camarillo farm to retrieve the cars of loved ones and speak to managers about what happened. Relatives of Jaime Alanis, who has worked picking tomatoes at the farm for 10 years, said he called his wife in Mexico during the raid to tell her immigration agents had arrived and that he was hiding with others inside the farm.

"The next thing we heard was that he was in the hospital," Juan Duran, Alanis' brother-in-law, said in Spanish, his voice breaking.

It was not immediately clear how Alanis was injured. A doctor told the family that others who brought Alanis to the hospital said he had fallen from the roof of a building.

Alanis had a broken neck, fractured skull and a rupture in an artery that pumps blood to the brain, said his niece Yesenia, who didn't want to share her last name for fear of reprisal.

"They told us he won't make it and to say goodbye," Yesenia said, crying.

The hospital did not immediately respond to requests for comment.

Confrontation with authorities

After immigration agents arrived at Glass House's farm in Camarillo on Thursday morning, workers called family members to let them know authorities were there. Relatives and advocates headed to the farm some 50 miles (80 kilometers) northwest of downtown Los Angeles to try to find out what was going on, and began protesting outside.

Federal authorities formed a line blocking the road leading through farm fields to the company's greenhouses. Protesters were seen shouting at agents wearing camouflage gear, helmets and gas masks. The billowing smoke drove protesters to retreat. It wasn't clear why authorities threw the canisters or if they released chemicals such as tear gas.

Ventura County fire authorities responding to a 911 call of people having trouble breathing said three people were taken to nearby hospitals.

At the farm, agents arrested workers and removed them by bus. Others, including U.S. citizens, were detained at the site for hours while agents investigated.

The incident came as federal immigration agents have ramped up arrests in Southern California at car washes, farms and Home Depot parking lots, stoking widespread fear among immigrant communities.

Federal investigations

The Department of Homeland Security said in a statement Friday that the investigation into immigration and potential child labor violations at the farm is ongoing. No further details of the allegations were provided.

The agency said hundreds of demonstrators attempted to disrupt the operations, leading to the arrest of four Americans.

"We will prosecute to the fullest extent of the law anyone who assaults or doxes federal law enforcement," Assistant Secretary Tricia McLaughlin said in a statement.

Immigration and Customs Enforcement and Customs and Border Protection were both part of the operation, the statement said.

Family members search for answers

Relatives of other workers said they got similar calls Thursday. The mother of an American worker said her son was held at the worksite for 11 hours and told her agents took workers' cellphones to prevent them from calling family or filming and forced them to erase cell phone video of agents at the site.

The woman said her son told her agents marked the men's hands with ink to distinguish their immigration status. She spoke to The Associated Press on condition of anonymity because she feared reprisals from the government.

United Farm Workers said in statement that some U.S. citizens are not yet accounted for.

Maria Servin, 68, said her son has worked at the farm for 18 years and was helping to build a greenhouse. She said she spoke to her son, who is undocumented, after hearing of the raid and offered to pick him up.

"He said not to come because they were surrounded and there was even a helicopter. That was the last time I spoke to him," Servin, a U.S. citizen, said in Spanish.

She said she went to the farm anyway but federal agents were shooting tear gas and rubber bullets and she decided it was not safe to stay. She and her daughter returned to the farm Friday and were told her son had been arrested Thursday. They still don't know where he is being held.

"I regret 1,000 times that I didn't help him get his documents," Servin said.
