A brush fire lit up hills northeast of downtown Los Angeles early Tuesday before firefighters and helicopter water drops contained the flames.

The predawn blaze began as three separate spot fires in the El Sereno area, said Fire Department spokesperson Brian Humphrey.

There were no reported injuries and structures were not damaged in the process.
