Firefighters were working Friday evening to free an injured woman from the wreckage of pickup truck which struck a tree in Porter Ranch.
Los Angeles Fire Department paramedics and firefighters responded at 10:39 p.m. to 10740 Vanalden Ave. where they found the driver trapped in the pickup truck, said LAFD spokesman Brian Humphrey.
The woman is expected to be taken to a hospital in critical condition, Humphrey said.
No one else was injured in the crash.
