A special investigation team of the Kozhikode Crime Branch-Crime Investigation Department will shortly file a charge sheet in connection with a bomb explosion at Narikkateri in Nadapuram here in February last.

The case relates to five persons getting killed and six others sustaining serious injuries, when the steel bombs which they had manufactured went off at an uninhabited house at Narikatteri in the night on February 26. All of them owed allegiance to the Indian Union Muslim League (IUML), the police said.

A 15-member team led by former Crime Branch Superintendent of Police C.M. Pradeepkumar, which investigated the case, had then recovered from the blast site 25 unexploded steel bombs, five kg gun powder, and raw materials for making explosives.

As many as 31 persons, including Thayyil Moidu, brother of IUML leader Soopy Narikkatteri, have been named accused in the case. As many as 20 were arrested but six were still absconding, investigators told The Hindu here on Thursday.

Now the case is being supervised by Crime Branch SP Neeraj Kumar Gupta, who has recently taken charge. The charge sheet will be submitted at the Nadapuram Judicial First Class Magistrate Court and then committed to the District Sessions Court here.

However, the investigation team will also have to obtain reports of the forensic science laboratory in Thiruvananthapuram on the samples on the debris and explosives. Besides, a report from the District Collector on the Explosive Substances Act, stating that the accused had no licence to manufacture and store explosives, has to be obtained.

A sanction is needed from the Home Department for prosecuting them under Section 153 A ( promoting enmity between groups on grounds of religion, race, place of birth, residence, and language and doing acts prejudicial to maintenance of harmony) of the Indian Penal Code. All of the accused have also been charged under Section 3 (punishment for causing explosion likely to endanger life or property) of the Explosive Substances Act.
