Arrest made in connection with Palisades Fire investigation in Southern California, source says

LOS ANGELES — An arrest has been made in connection with the Palisades Fire, which caused widespread destruction in Los Angeles County and killed a dozen people earlier this year, sources close to the investigation confirmed to ABC News.

The U.S. Attorney’s Office, along with the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Los Angeles Police Department are expected to hold a press conference at 9 a.m. Wednesday.

An official cause still hasn’t been determined for the January wildfire that burned nearly 8,000 structures and killed 12 people.
