Man intervenes in siblings' stabbings at Oakland BART station

BART Police Chief Carlos Rojas gave a personal thank you Monday to Oakland landscaper David Harris-- a man he calls a hero.

"Bravery without a doubt. Had he not acted, we could be investigating a homicide," said Rojas.

"Heroes are for first responders and people who do it every day. I just got lucky," said Harris.

Harris still has bandages covering cuts on his fingers on both hands. They are battle wounds he received when he helped stop a BART passenger who was randomly attacking two passengers with a knife near the station agent booth at the Oakland Coliseum BART Station Saturday afternoon.

Harris says he was putting additional money on his Clipper card.

"I heard a woman screaming. Looked around toward the agent's booth and saw she was getting stabbed. I ran over, took control of his wrists, got the knife away from him and brought him, to the ground," said Harris.  

"I didn't have time to be scared. I just reacted,"

Another Good Samaritan is seen on cell phone video helping to hold down 32-year-old Robert Dolph until police arrested him.

"We turned him on his back. He was still resisting," said Arturo Garcia, who says he was just passing by and decided to help..

Garcia and Harris said Dolph wasn't making any sense when he spoke.

Dolph was arrested on two counts of attempted murder. Police say he confessed, but did not offer a reason for the attack.

Harris says he too was a victim of a stabbing some 20 years ago in his San Francisco apartment building.

"A hallway full of people and no one did anything. I just felt I wouldn't want anyone to feel lke that," he said.

The victims are described as a woman in her 50s and her brother who is in his 60s. 

The woman victim has been released from the hospital, but her brother is still in critical condition.

Harris says he would like to meet them. "I'd just let them know there are people who care," he said.
