A woman has been arrested on suspicion of premeditated murder after she was accused of poisoning a friend using cyanide in Ratchaburi, central Thailand, with police saying they are also investigating the circumstances of nine further deaths.
The accused, identified in Thai media as Sararath Rangsiwutthiporn, or Am, had travelled with her friend, Siriporn Khanwong, known as Koi, to make merit by releasing fish at a pier in Ratchaburi on 14 April.
