Chula Vista Police are looking for the public's help in identifying a man wanted for questioning in connection to an unprovoked attack on a victim.
The man, pictured in March 2015, is wanted for his involvement in the attack, police said. Authorities did not provide any information on the attack.
The victim continues to suffer from severe injuries sustained during the attack, police said.
Lt. Fritz Reber with Chula Vista Police told NBC 7 there was approximately a minute of the attack which was not recorded on camera.
Reber said the victim had been listening to music on the bus when the suspect got up and challenged him. At this point, it's unclear what exactly the suspect said.
The victim did not respond to the suspect and continued to ignore him.
"It was unprovoked and fairly violent," he added. "Victim suffered pretty severe injuries."
Ben Villa, a commuter who rides the bus said it is heartbreaking that no one helped the victim during the attack.
"Society is just so worried about themselves in these days, forget there are other people out there in situations," Villa said, adding that if he had been there, he would have grabbed the suspect to stop him.
Reber said they are investigating this as a possible hate crime.
"Certainly there is a hate crime component. Victim had some indication perhaps the attack was result of sexual orientation," he said. "So that's a concern."
Anyone with information on this man’s identity is asked to contact the Chula Vista Police Department at (619) 691-5151 or Crimes of Violence at (619) 691-5178. You may also call 422-TIPS if you wish to remain anonymous.
No other information was immediately available.
