Liam Trimmer, a UK man, died while celebrating his engagement in Australia.

Liam Trimmer, 29, sliced a carotid artery in his neck during an accident at his house in Western Australia (WA) on Sunday.

Although loved ones attempted to revive him, Mr Trimmer died shortly before paramedics arrived, according to officials.

According to colleagues, the senior constable was a “extraordinary officer” who “loved helping his community”.

“This is a really tough time for WA Police,” Commissioner Col Blanch told local media on Monday, describing Mr Trimmer as a “capable young man with his whole life ahead of him”.
