Police were evacuating people Tuesday evening at Disneyland's Toontown after a report of an explosion that appeared to have involved dry ice, authorities said.
No injuries were reported in the blast, which was called in about 5:30 p.m, Sgt. Robert Dunn of the Anaheim Police Department said.
"As a precaution we have evacuated Toontown," Dunn told The Times.
He said the dry ice appeared to have been placed in a plastic bottle. Officers on the scene were gathering evidence.
A bomb squad from the Orange County Sheriff's Department was responding. No other details were immediately available.
