Thailand police arrests Australian man after teen’s body found in suitcase

An Australian man detained at Thailand’s largest international airport has been accused of attempting to leave the country while suspected of murdering a 17-year-old girl and dumping her naked body in a suitcase at the side of a railway.

Thai police discovered the body of the 17-year-old, identified in news reports as hailing from Kalasin province in the country’s north-east, inside a black suitcase abandoned next to railway tracks.

The Foreign, Commonwealth and Development Office (FCDO) has been in contact with Thai authorities while police officers are "gathering as much information as possible".
