Most assaults occurred in 2010 (16.2%) and 2011 (17.5%). The age group 6 to 12 years accounted for higher rate (49%), mostly in males (71.8%). A total of 83.3% of the victims belonged to low social class, and 72.3% of the victims were out of school. Only 1.9% of the victims had a mental disability.
