Anonymous person donated about one billion for SIDR affected people

I have just hear the news over our local TV channels that one anonymous person has donated about one billion for SIDR affected people in the coastal belt of Bangladesh. The exact amount donated is 9000 million in local currency (Bangladeshi Taka).
The person is willing to be anonymous. So no identification (even nationality) is not disclosed. It's the biggest amount donation so far for the SIDR affected people.

I did a google search few minutes ago. But couldn't find out the news on the net yet. Hopefully the news medias will disclose more details soon.

May Allah bless him.
