A police search on the underground BART tracks in San Francisco's Mission District on Wednesday evening temporarily halted rush hour train service through much of The City, a BART spokeswoman said.
San Francisco police began chasing a suspect on the tracks shortly before 5 p.m. between the 16th Street Mission and 24th Street Mission stations, BART spokeswoman Alicia Trost said.
The search prompted the shutdown of all BART service between the Powell and Daly City stations, Trost said.
Trains heading into San Francisco were turning around at the Montgomery station and heading back toward the East Bay, Trost said.
BART resumed service shortly before 5:30 pm, but it was warning about residual delays from the earlier shutdown.
