The zoological society is now calling for greater restrictions on the extensive fireworks displays that are a trademark of Bonfire Night, also known as Guy Fawkes Night, the Nov. 5 celebration named after a participant in a failed plot in 1605 to kill King James I.

The three-month-old red panda cub named Roxie died on Bonfire Night at her enclosure. The Royal Zoological Society of Scotland (RZSS), which runs the zoo, has said there was “probably” a link to fireworks being let off in the city centre and the death.
