The only mention of a carer I can find is speculation.
One witness told the Mail on Sunday the man, who had a mobile phone and was wearing AirPods, appeared to 'psyche himself up' by performing a 'dance' in the spectator area.
Speaking to The Mirror, one woman said she saw him dancing with his AirPods in around 20 minutes before the horror incident.
"The man who I saw on the bridge with his AirPods in dancing was happily enjoying seeing the tiger,” she said. “He obviously wasn't with anyone and he asked a total stranger to take a picture of him with the tiger in the background.
"Probably the last photo on his phone. I'm not sure if he was with a carer or family member but I honestly do think he just wanted to play with the tiger.
