Ottered

In Singapore, a man was attacked and badly bitten by a group of otters (https://www.theguardian.com/world/2021/dec/10/i-thought-i-was-going-to-die-otters-attack-british-man-in-singapore-park). Otters are carnivorous Mustelidae like weasels, badgers, mink and wolverines. Social groups of Asian otter species would be quite formidable. It seems quite clear, from the account, that the otters were startled into attacking their 'victim'. It was early morning and a shouting runner had just sped towards them. The victim appears to have been an unlucky, slower-moving target of the group's defensive behaviour. It's to be hoped that humans and otters can coexist in Singapore parks.
