A giraffe seen trying to escape from a transporter at a Hampshire service station has died.
Eight-year-old Rothschild giraffe Kwaheri suffocated in what appeared to be an allergic reaction to a sedative.
The male giraffe was being transported from Longleat Zoo to Port Lympne, Kent, to take part in a breeding programme.
Police were called to Buck's service station on the A303 near Winchester on Tuesday after reports that the 18ft (5.5m) animal was on the loose.
The driver had aborted the trip after part of the roof canvas became damaged, Longleat Safari Park said in a statement.
During the return journey the giraffe developed breathing problems due to regurgitation, which may have been caused by an allergic reaction to the sedation administered for the transit.
The statement added: "Kwaheri was checked on the day and he was deemed fit and well."
Keith Harris, head of Safari Park at Longleat, said: "This appears to have been a tragic accident.
"Having moved giraffes all over Europe without incident we are obviously very upset by this tragic death and obviously will be investigating further to ensure that this does not happen again."
