At least 37 people were killed, most of them Christians.
The administration had provided shelters to the riot victims, setting up 13 relief camps in the district.
'Eleven of them have now been closed down,' Kumar said.
He said nearly 700 victims are, however, still taking shelter in two relief camps -- one at Mandakia and another in Tiangia village, though no violence has been reported in the region since October last year.
'Efforts are on to send the remaining people back to their homes soon,' the official said.
