Police are investigating after receiving a report of explosives in a car in downtown Los Angeles on Saturday, the Los Angeles Police Department tells NBC4 Investigates.

A caller contacted an undisclosed federal agency to alert officials of explosives in a car near the intersection of West 5th and Figueroa Streets. After receiving the report, the agency alerted LAPD of the call, prompting the department to investigate.

“This appears to have nothing to do with the marathon,” police said in a statement. “The LAPD will continue to work with their federal partners to ensure the safety of the runners and spectators and take all of these incidents seriously.”

Police did not confirm if explosives were found at the site. The investigation remains ongoing.
