A U.S. Immigrations and Customs Enforcement agent lost a pistol Friday morning in San Francisco, police said.
At 9:27 a.m. a San Francisco police officer at the Ingleside District Station took a call from the agent who said he lost his pistol at 6 a.m.
As of Saturday, further details about the incident remained sparse.
"A duty weapon belonging to a special agent with U.S. Immigration and Customs Enforcement was reported missing Friday morning in San Francisco," ICE spokesman James Schwab wrote in an email.
He continued: "The incident was properly reported through official federal channels and to local authorities. The matter is currently under investigation."
In the past year, a number of law enforcement officers have lost their weapons.
The gun that killed Kate Steinle in San Francisco in July 2015 was stolen from a vehicle of a U.S. Bureau of Land Management ranger.
The University of California at Berkeley police chief had her gun, badge and official laptop stolen from her car on Aug. 21 at Point Isabel in Richmond.
A bill introduced in the state Senate last month would require everyone, including law enforcement officers, to store any handgun left in a vehicle in a locked trunk or a locked container out of sight.
