San Francisco police are searching for the gun of a federal agent who lost the weapon after he left it on top of his car and drove off.

KGO-TV reports the Immigration and Customs Enforcement agent's loaded service weapon was reported lost in the Ingleside neighborhood Friday morning. Police say it's an H&K P200sk .40 caliber handgun.

In the last eight months, handguns stolen from federal agents were used in the high-profile slayings of Kate Steinle in San Francisco in July and muralist Antonio Ramos in Oakland in September.

Last month, three handguns were stolen from an FBI vehicle parked in a residential neighborhood in Benicia.
