A 10-acre brush fire in the Sepulveda Basin that threatened nearly 100 homeless people's belongings was under control Tuesday afternoon, the Los Angeles Fire Department said.
The fire that first began shortly before 4 p.m. forced the closure of the Metro Orange Line busway Tuesday.
Investigators were also looking into propane tank explosions that sent bursts of flames into the air as crews battled the blaze.
The Metro Line was closed between White Oak and Woodley avenues, according to the Los Angeles Fire Department.
The large grass fire was reported near Victory Boulevard which remained open in both directions.
Though the fire burned belongings of homeless people in the encampment, no one was injured.
Burbank Boulevard between Balboa Boulevard and the 405 Freeway was temporarily shut down as firefighters worked to extinguish the flames.
