A woman died Thursday after falling down an escalator at the Montgomery BART station in San Francisco, officials said.

The woman, identified by the city medical examiner as Oakland resident Yanira Funes, fell shortly after 10 p.m., according to a BART police log. She was headed from the concourse to a downstairs platform at the time, said Chris Filippi, a BART spokesman.
