Train service is delayed and recovering in all directions around the19th Street Oakland BART station, after the station was closed for nearly an hour while police investigated a bomb threat.

At 12:48 p.m., BART Police received a telephoned bomb threat, said Anna Duckworth, a spokeswoman for the transit agency. Police swept the station with K9 units. At 1:28, the station reopened. “They did not find any credibility to the threat,” Duckworth said.

The trains were not being allowed to enter the station while police investigated. Major delays are expected in all directions as the system recovers, and parallel service was being offered on the A/C Transit Bus #6 and 18.

Duckworth said that police are “in contact with a possible suspect.” She did not know whether the suspect has been arrested.
