There is nothing alarming but there are indications of some places (which could be targeted)," Thrissur Range IGP MR Ajit Kumar, one of the investigating officers, told reporters after visiting the site of the blast. "Some pamphlets have been recovered. There was a map of India and they had written certain things in connection with the recent developments in the country," he said.
