Rahman used the pen name Kucchit Hasher Channa, or Ugly Duckling. Two students from an Islamic school were arrested by police. The two said they didn't know about Rahman's writing and they didn't know anything about blogs. Someone told them to kill Rahman as a religious duty. One of the attackers traveled from Chittagong and stayed overnight at a mosque. The other attacker was from an Islamic school in Dhaka. Rahman had a page on Facebook that said "I am Avijit", meaning he was a supporter of Avijit Roy, a Bangladeshi-American blogger who was killed a month earlier.
