A day after the Bombay High Court confirmed the death sentence to Ajmal Qasab in the 26/11 terror attack case, the Pakistani terrorist has withdrawn into a shell and does not talk to any guards in Arthur Road Jail here, prison sources said on Tuesday.

After hearing the verdict in the video conference room of the prison, Qasab returned to his cell and did not show any signs of being tense or feeling dejected. He did not talk to anyone and slept well after having dinner, the sources said.
