Pregnant teen attack on bus prompts increased security

The video footage, which was first seen on KOMO News, is shocking, even for the most seasoned deputies. Five girls jumped the victim in the back of the bus. The camera captured every blow.

"I saw my whole face was like bleeding, and I was like, 'Oh, my goodness!' And it's dripping and stuff," said the victim, Jessica.

The girls were seen grabbing Jessica's MP3 player out of her hand. Jessica is seen pleading with the girls to stop, telling them she's pregnant.

"One of them kept kicking me in the back and stuff. And you know, I didn't want anything to happen," she said.

But the fists keep flying, and Jessica says not a single passenger tried to help.

Sheriff Sue Rahr can't believe nobody on board called 911. When the bus driver eventually did call 911, the attack was already over.

"I'm shocked," said Rahr. "Frankly I think people were so shocked that it took them a while to process what was happening."

Now Rahr is calling for beefed-up security, including additional cameras on board.

One out of every four Metro buses are already equipped with cameras, and there are plans to install another 250 next year.

But will they really deter criminals?

Today, I took a ride on the Route 358 bus from north downtown Seattle to Aurora -- the same route Jessica took.

Riders said while they like the idea, cameras won't stop the violence because people don't want to get involved.

"On these buses in Seattle, people see so much crazy stuff. If it doesn't have anything to do with them, they don't want no parts in it, you know," said one rider.

But in this case, the bus camera captured the faces of all of the suspects, allowing detectives to identify and arrest all five of them.

Transit police urges anyone who witnesses a fight aboard a bus to resist stepping in call 911 instead.
