At least 20 Los Angeles police cars sped to Bruno Street in Chinatown on Thursday night after getting a call that a gunman was holding several people hostage inside a building.
The caller said the person had a handgun.
"We cannot confirm whether that's credible or not," Vanegas said. The information was "secondhand."
Police at the Central Division called the incident a "kidnapping in progress" but had no immediate details.
