(CNN) More than 1,000 guns were found in a home in the upscale Los Angeles neighborhood of Holmby Hills, but authorities said there was no indication they were used in crimes.

"At this time, there is no indication they were, but that could change as the investigation continues," Ginger Colbrun, spokeswoman for the Bureau of Alcohol, Tobacco, Firearms and Explosives, said Thursday. Authorities will trace all the weapons, she said.

ATF agents and Los Angeles police officers on Wednesday executed a search warrant in an investigation of someone suspected of manufacturing and selling illegal firearms, Los Angeles police Officer Jeff Lee said.

The property resembled "a hoarder's house" and it took 30 law enforcement officers more than 15 hours to clear the house and remove all the weapons, a law enforcement official familiar with the investigation told CNN.

Police also searched a home about 15 miles away, near Chinatown, the source said.
