Agents from the FBI and U.S. Secret Service descended on homes in Burbank, La Crescenta and La Cañada Flintridge on Wednesday where they conducted early-morning raids on the residences.

Authorities simultaneously carried out the raids around 6 a.m. after receiving federal search warrants for homes at 512 S. Via Montana in Burbank, 3122 Pontiac St. in La Crescenta and 1435 El Vago St. in La Cañada.

Laura Eimiller, a spokeswoman for the Federal Bureau of Investigations, said the details and targets of the raids were unavailable because a judge sealed the contents of the warrants.

Property records show that the homes in Burbank and La Cañada are owned by Alen and Dina Gharehbagloo, while the home in La Crescenta is owned by Robert and Dana Khudaverdyan. It’s unknown what connection, if any, the four had to the raids.

Attempts to contact Alen Gharehbagloo were not returned as of press time.

A number associated with Robert Khudaverdyan was answered by a woman who did not wish to identify herself and who said he was unavailable for comment.

When the woman was informed about the raids, she responded, “OK, thank you, bye-bye” and promptly hung up the phone.

Eimiller said the raids were conducted jointly by the FBI, Secret Service and Los Angeles Police Department.

Requests for comment from the Secret Service were not returned by press time, and the LAPD directed all inquiries to the FBI.

Officers from the Burbank Police Department and deputies from the Crescenta Valley Sheriff’s Station were also present at raids in their respective jurisdictions.

Burbank Lt. Mitch Ross said officers were at the raid to provide a uniform presence in the neighborhood and to provide any assistance, if needed. However, he said officers did not actively participate in serving the warrants.
