Newly released video shows the moments leading up to a mob-style attack on a BART train at Oakland’s Coliseum Station last April.

The video taken on April 22 shows about 40 teens jumping the fare gates and pushing through the emergency gates at the station as an overwhelmed station agent calls for help.

Shortly after the video was taken, the mob gets on a train with Rusty Stapp, his wife and their 18-year-old daughter.

KRON4’s Maureen Kelly talked to Stapp, who was beaten and robbed that night. He says this crime illustrates how the transit agency needs to do more to keep passengers safe.

“Three of them jumped on top of me,” Stapp tells KRON4. “Two of them were swinging at me, one of them was kicking at me. I released my phone and at that point they got off of me.”

Stapps, who sustained bumps and bruises in the attack, says the mob went down the car and robbed other people.

Someone also reached over and stole his wife’s purse.

BART is now saying that two juveniles and one 18-year-old were arrested.

The 18-year-old copped a plea deal and did one year in jail.

Stapp slapped BART with a $3 million lawsuit.

He says the ease in which the fare gates are jumped makes it too easy for criminals to enter and exit the station.

“I’ve traveled all around the world and I’ve never seen a system that you can enter and exit as easily as this, nor have I ever felt is unsafe in the system as I do on BART,” Stapp says. “And I’ve traveled all throughout Asia and all throughout Europe and I’ve never seen a system like this.”

A BART spokesperson could not comment on the lawsuit but says transit systems with tougher to jump fare gates still experience fare evasion and crime.

BART officials have taken steps like installing higher fencing and putting alarms on the emergency gates at some stations.

They are also conducting a study on changing the gates to make it harder for people to evade paying their fare without slowing down commuters as enter and exit the stations.
