A British woman has reportedly been stabbed to death in a park in Cambodia's capital, after allegedly being caught up in a love triangle with her killer.

Jessica Cariad Hopkins, 34, is said to have died from multiple stab wounds in Phnom Penh's Chamkarmon district just before midnight on Friday.

Local cops arrested Congolese woman Kidikila Nganda Glodie and said they believed that Jessica's death was likely the result of a grisly love triangle.

She was found lying in a pool of her own blood in the park.

Glodie was found in a salon 1.5miles away from the scene of the murder at 4.30pm local time on Saturday.
