Los Angeles police seek to determine if water-bottle explosion was deliberate or accidental as theme park reopens as normal
Police are reviewing video footage and social media postings to determine if Tuesday's apparent dry ice explosion at Disneyland's Toontown was deliberate or accidental.
The Los Angeles theme park opened as normal on Wednesday and played down the incident which prompted the brief evacuation of families and the mobilisation of a police bomb squad. No one was injured.
"Review is complete. Mickey's Toontown has been deemed 'all clear' by local authorities. Guests are welcomed [sic] to return," the company said in a statement.
The dry ice appeared to have been packed into a plastic bottle and left in a rubbish bin, which contained the small blast.
"At this point we don't know if it was on purpose, or by accident, or if it accidentally got thrown away," sergeant Bob Dunn of the Anaheim police department told KTLA 5.
When dry ice is compressed in a plastic bottle it can explode.
Dunn said Disneyland used a lot of dry ice but he also noted that police often came across crude dry ice bombs in Anaheim. "These are very common, unfortunately, in our neighbourhoods."
Investigators are trawling social media postings and reviewing video surveillance footage for clues.
Toontown has cartoon-style architecture and includes the home of Mickey Mouse. It is popular with young children.
