A Border Patrol agent is suffering multiple head fractures after an illegal alien attacked him and bashed his head in with a rock, according to several Border Patrol agents who spoke with Breitbart Texas on the condition of anonymity. The attack occurred near the Ajo Station of the Tucson Sector.

The agent was new to the U.S. Border Patrol agency. According to the sources, the illegal alien tackled the agent and used a rock to bash the agent’s head.

A drug trafficking group was apprehended earlier in the day, according to the sources. When the agent was attacked, he reportedly deployed intermediate weapons such as OC spray and a baton. One Border Patrol agent source told Breitbart Texas, “After the Ferguson ordeal, agents are so apprehensive about using their firearm that incidents like these may become more frequent. Agents are so hesitant that it is actually risking our lives.”

One Border Patrol source told Breitbart Texas that the agent was taken by an air ambulance and is currently conscious with multiple severe head fractures.

Breitbart Texas will provide updates as they become available.
