Meanwhile， Mandalay Region Security and Border Affairs Ministry further identified the gunman as an ex-prisoner from Mandalay prison who was sentenced to 27 years' jail term for stealing Buddha statue， but was once released in 2014 under amnesty order after serving for 11 years' term.

The President's Office requested the public not to be stricken by panic and to stay quietly and peacefully to be careful of religious an racial incitement.


The NLD has condemned the assassination of U Ko Ni ， calling for prompt exposure of the masterminder behind the plot.
