Woman detained in 405 Freeway fire in Mission Hills

Police detained a woman Wednesday in connection with a small brush fire that forced the closure of a major freeway for more than an hour in the Mission Hills area.

Police said the woman, who was not identified, was detained as a person of interest and that arson investigators hoped to speak to her about the fire, which burned alongside the freeway as traffic zoomed overhead.

Authorities believe the woman may have been cooking underneath the 405 Freeway before the blaze broke out. No further details about her were provided.

The Los Angeles Fire Department said the fire broke out around 3 p.m., just north of Devonshire Street.

Video footage showed large flames and black smoke billowing from underneath the freeway.

The California Highway Patrol closed both sides of the 405 Freeway and the transition road to the 118 Freeway as the fire spread.

Traffic was clogged up for miles as firefighters battled the flames. No injuries were reported.

Authorities said the cause of the fire is still under investigation.

As of 5 p.m. all lanes of the 405 Freeway were reopened, including the transition road to the 118 Freeway.
