LOS ANGELES (AP) — Four young adults have been stabbed after a feud spilled out of a downtown Los Angeles nightspot.

Investigators say two men were arguing inside the Belasco Theater and the stabbing occurred at about 2:20 a.m. Friday outside the South Hill Street building. The nature of the dispute hasn't been disclosed.

City News Service says one of the men pulled out a knife and stabbed the other man. Three bystanders who tried to intervene were also stabbed.

A man in his 20s has been arrested. His name hasn't been released.

The wounded were taken to a hospital with non-life threatening injuries.

The Belasco Theater website describes the nightspot as a multipurpose event and entertainment complex with state-of-the-art sound and lighting systems.
