Police in Tustin are searching for the alleged suspects who robbed a member of the U.S. Secret Service at gunpoint prior to the agent returning fire.

It happened Saturday night around 9:40 pm, according to the Tustin Police Department.

After receiving reports of a possible robbery, officers responded to the intersection of Stratus Lane and Westwind Drive in the Tustin Fields residential community.

Officers found the victim, who identified himself as a member of the U.S. Secret Service and said his bag was stolen at gunpoint.

Anthony Guglielmi, chief of communications for the U.S. Secret Service, wrote in a statement to Newsweek:“A member of the U.S. Secret Service was the victim of an armed robbery in Tustin, California late Saturday when returning from a work assignment. The employee discharged their service weapon during the incident but unknown if the assailants were struck. We are thankful that the employee did not sustain any injuries.”

The agent was on route to a star-studded campaign fundraiser for Joe Biden in Los Angeles upon completing a work assignment in Tustin, California.

Some of the agent’s belongings have been recovered, police said, but the suspects remain outstanding.

Police say it’s unknown if any of the suspects were hit by the agent’s gunfire. A 2004-06 silver Infiniti FX35 or similar vehicle was seen leaving the scene, and police released an image captured by security footage as it drove off.

The Police Department is asking for the public’s help to identify those involved in the armed robbery. Anyone with information is urged to contact Detective Graciela Melendrez by email or by calling 714-573-3372.
