Late Friday, San Francisco police reported a break in the case of an attack on a Muni train station agent just one day after they asked the public for help.
They said they arrested Devon Riley, 20, of San Francisco following a tip.
On Thursday, San Francisco police released a video of the Oct. 10 incident in hopes of finding the person responsible for the attack.
The agent was attacked at the Van Ness station after telling a man on his bicycle that bikes weren't allowed on trains. The suspect ignored the warning and instead, lifted the bike over the railing. The agent followed the suspect to the platform when the suspect suddenly turned around and began punching and kicking him. The agent's injuries were considered serious.
On Friday, the San Francisco Community College District Police Department said they received an anonymous tip that the suspect was on campus.
Officers from the San Francisco Muni Task Force responded to the tip and took Riley into custody.
He was booked on the following charges:
- battery with serious injuries
- battery on a transportation operation
- mayhem
