 Chunee became dangerously violent towards the end of his life, attributed to an "annual paroxysm" (perhaps his musth) aggravated by a rotten tusk which gave him a bad toothache.On 26 February 1826, while on his usual Sunday walk along the Strand, Chunee ran amok, killing one of his keepers.He became increasingly enraged and difficult to handle over the following days, and it was decided that he was too dangerous to keep.
