Non-active Jakarta Governor Basuki "Ahok" Tjahaja Purnama now has a new activity to keep him busy during his detention at the Mobile Brigade Command detention center (Mako Brimob) in Kelapa Dua, Depok, West Java. 

He spends most of his time replying to letters from his supporters, said his sister cum lawyer Fifi Letty Indra. 

"There are hundreds of letters arriving everyday. Some people also send books, cards and others," she said as quoted by kompas.com on Tuesday. 

The letters, she said, make him as busy as when he was still an active governor. 

"He's as busy as when he still worked at City Hall. He used to check documents but now he checks mail," she added.

She said that Ahok was happy to receive the mail, which has become a form of support during his detention. 

Among the letters was one from a 12-year old child named Allegra Freya Berlianawan. Both Allegra's and Ahok's letters have gone viral on social media. (agn)
