A Japanese woman fell to her death from her room on the 20th floor of a condominium on Soi Sukhumvit 49 in what believed to be suicide.
Security officers of the 26-storey luxury condo alerted police at 6:45am that a foreign woman was killed in the fall.
She was identified as Emi Kato, 35. Her body was sent for a post-mortem at the Chulalongkorn Hospital.
Police checked her room and did not detect any sign of foul play.
