BANGKOK (AP) — Thai police are investigating after the body of a foreign woman was found at a secluded spot on the southern island of Phuket on Thursday. Thai media, quoting police, said the dead woman was a 57- year-old Swiss national.

The reports said the woman’s partially clothed body was lying face down in a rock crevice near a waterfall and appeared to have been concealed by a sheet.

Video shot at the scene Thursday showed investigators inspecting clothing and personal documents.

The dead woman’s name has not yet been officially released.
