Yesterday afternoon, a loud bang in Disneyland L.A.’s Toontown section caused an evacuation and investigation by Ahaheim police. A bomb squad later determined that the blast was caused by a dry ice bomb made out of a plastic bottle that went off in a garbage can. No injuries or damage to park property were reported.

Today, the Anaheim police have announced that a Disneyland “cast member” (employee) has been arrested in connection with the incident. 22-year-old Christian Barnes of Long Beach, who was working at the park as an outdoor vendor, was identified as a suspect using surveillance footage. He has now been arrested on suspicion of possession of a destructive device and his bail has been set at $1 million.

Barnes, who sold soda and water at the park, has not provided a motive for the incident. Anaheim police have stated that Barnes is cooperating with the investigation, and that he told them the bomb was an “isolated incident with unanticipated impacts.”
