Man in tube closes BART for 90 minutes

(10-14) 20:48 PDT -- BART service through the Transbay Tube has been restored after it was shut down Sunday evening for about an hour-and-a-half after surveillance cameras showed someone walking into the tunnel beneath the bay.

According to BART spokesman Jim Allison, a man "in normal attire walking casually" was spotted entering the tube from the Embarcadero station at about 6:46 p.m. BART immediately shut down the Transbay Tube and sent a train full of police officers inside. They found and arrested a person at 7:44 p.m., he said.

Lt. Tyrone Forte said he was found about half way between Embarcadero station and West Oakland station.

Service was restored at about 8:15 p.m., Allison said, after BART police thoroughly inspect the tube to make sure it was safe to start running trains.

The tube is outfitted with surveillance cameras and other security devices aimed at protecting it against terrorists, vandals or someone deciding to take a stroll. BART police don't yet know why the man entered the tube.

"We're still looking into that," Forte said. "But we have the man in custody."

No more details are available. BART reopened the tube just in time for the end of the San Francisco Giants game, which was expected to send crowds of fans heading home from AT&T Park.
