The United States Department of Homeland Security has opened an investigation into allegations a US Border Patrol agent fired a gun into a video game controller during an event on Saturday.
A spokesperson for the US Department of Justice said it was investigating the claims of a “civil rights violation” by an unnamed US Customs and Border Protection agent.
The spokesperson said in a statement: “We have requested a full investigation and are continuing to gather information.”
The spokesperson did not provide further details.
The Border Patrol was due to hold a counter-terrorism training event at the port of Laredo, Texas, on Sunday.
It is not clear if the incident involved an employee or a Border Patrol officer.
Border Patrol agents have been on the ground in the US since 2009, when President Barack Obama said border security was a “top national security priority”.
The incident happened on Saturday in Laredos port area, just west of the Rio Grande.
It was unclear how many people were at the event.
An online video from the event showed a group of gamers playing Borderlands, an open-world video game released in 2008.
The video showed a customs agent standing by with his firearm drawn and the player with the controller in a chair.
The player is then seen pointing the controller at the agent.
Border Protection said in the statement that it is investigating the incident and the agent is no longer with the agency.
