Kochi: Writer KP Ramanunni has received a letter threatening him that his hands will be chopped off if he does not convert to another religion within six months.

The letter says that his hands will be chopped off similar to what was done to TJ Joseph.

The letter points to articles written by Ramanunni about Islam. "The articles mislead innocent believers and hence we do not intend to show any mercy," the letter warns.

Ramanunni received the threat letter six days back. Police have started a probe on Ramanunni's complaint.
