Police arrested a gunman who threatened to open fire inside the Los Angeles Times building on Friday night.

The unidentified gunman was on the third floor of the building located at 1st and Spring streets when he said he would start shooting and that he did not mind killing, witnesses said according to Reuters.

Police arrived on the scene after receiving a call a little after 7 p.m. The Los Angeles Police Department, which is headquartered across the street from the building, arrested the man less than an hour later. No gun was on him.

The suspect is said to be in his 20s and works for a company called Vxi Global Solutions that rent's office space in the building, the LA Times reported.

Witnesses told the LA Times the suspect said he was depressed, did not mind taking people's lives and that he did not want to go to jail. The man also allegedly gave one person a bag of bullets.

"We don't know if he had a gun," one witness, Jae Valdes, told KTLA TV. "He just supposedly hide a gun and bullets somewhere."

The radio call to police was made after a text message from inside the building said someone was "about to start shooting," detective Gus Villanueva told the Associated Press.

The newspaper's building was put on lockdown until around 9 p.m. as police searched for a weapon, but none was found, Lieutenant Lonnie Benson said according to the AP.

A request for comment from Vxi Global Solutions was not immediately answered, the AP reported.

The LA Times has been at the downtown building since 1935. Vxi Global Solutions provides customer service via phone for other businesses, the AP reported. Other companies and government agencies also rent office space from the newspaper.
