Police were informed at 5am that the woman, identified as Veronika Kobzova, had died at Chalong Hospital from injuries sustained in a fall.
Officers from Chalong Police Station, led by Pol Lt Kriangkrai Daokrajai, responded to the report and proceeded to the scene at villa estate, off Soi Sainamyen in Chalong.
Witnesses told police that the incident occurred around 3:30am. Ms Kobzova had been drinking beer and was reportedly intoxicated when she began walking along the edge of a rooftop swimming pool at a villa at the resort. She slipped and fell from the third floor into an alley beside the building.
Two women present at the time ‒ Karina Zemliankina, a fellow Ukrainian, and her Thai friend Mesinya Kunasangkam ‒ immediately called for emergency assistance. Ms Kobzova was rushed to Chalong Hospital, arriving at 4:02am, but was pronounced dead by a doctor at 4:28am. Medical staff believe she died before reaching the hospital.
She was found wearing a cream-coloured shirt and short skirt. According to police, she suffered fatal injuries to her head and chin consistent with a high fall.
Police said Ms Kobzova’s boyfriend and other friends at the scene did not suspect foul play.
Her body was sent to Vachira Phuket Hospital for a post-mortem examination. Forensic officers will conduct a full inspection of the scene, and the Ukrainian Embassy has been notified, police said.
