Around 9:15 a.m., BART closed the Richmond Station and detained one of many people protesting U.S. Immigration and Customs Enforcement policies.
Two other protesters were detained by Richmond police, BART spokesman Linton Johnson said.
As of 10:15 a.m., officials had reopened the Richmond Station but the Fruitvale, Coliseum and West Oakland stations in Oakland were shut down because anywhere from 60 to 100 protesters were jumping the entrances, Johnson said. Trains were running through the stations but not stopping.
By 11:45 a.m., all stations were back in service but, "as long as these actives affect the safety of our patrons, BART may need to make the decision to close stations as necessary," BART spokeswoman Luna Salaver said.
