One person has died from "injuries they sustained as a result of yesterday's immigration enforcement action" in California, United Farm Workers said on Friday.

       Federal agents clashed with protesters during an immigration raid at a farm in Ventura, one of at least two large-scale raids in Southern California on Thursday.

       The incident occurred outside of an agricultural farm along Laguna Road in the Camarillo area of Ventura County.

       The union, in a series of posts on Friday, confirmed some farmworkers were critically injured during the enforcement operation.

       "Others, including US citizens remain unaccounted for," UFW said in a post.

       ABC News' Los Angeles station KABC, reported the man was Jaime García. Earlier in the day, KABC spoke with a family member who said he fell about 30 feet off a building while he was possibly trying to run from federal agents.

       "This man was not in and has not been in CBP or ICE custody. Although he was not being pursued by law enforcement, this individual climbed up to the roof of a green house and fell 30 feet. CBP immediately called a medivac to the scene to get him care as quickly as possible," said Department of Homeland Security Public Affairs Assistant Secretary Tricia McLaughlin.

       Garcia suffered a broken neck and skull, according to KABC.
