The first source is Anawrahta of Launggyet, son in law of King Minkhaung I of Ava.
Anawrahta was appointed governor of Arakan in 1406, and later married to the king's daughter Saw Pyei Chantha.
In April 1408, Razadarit's Hanthawaddy troops captured Launggyet (Arakan's then capital), and took Anawrahta and Saw Pyei Chantha prisoner to Pathein.
On arrival, Anawrahta was executed, and his wife passed into Razadarit's harem as a full queen.
Nawrahta lived in the palace so he was easily caught; being of royal blood, he was drowned.
