One of the committees formed to investigate the October 20 mayhem at Borhanuddin upazila in Bhola submitted its report on Saturday.
Formed by the Bhola district administration authorities, the three-member committee submitted the report to Bhola district Deputy Commissioner (DC), Masud Alam Siddique.
However, neither did any of the probe committee members nor the DC disclose the findings of the 15-page probe report due to restriction from the higher court.
But sources said, the probe bodies tried to find out the motive behind the attack and identify those who attacked police, local people of Hindu community and also Hindu temples.
Headed by Mamudur Rahman, a Deputy Director of the Local Government office in Bhola, two other members of the committee were Atahar Miah, Additional DC of Bhola, and Muhasin Al-Faruq, an Additional Superintendent of Police in Bhola.
The report was supposed to be submitted within three working days. But the time limit was extended for two more working days for better investigation, said the probe committee members.
After receiving the probe report, the Bhola DC said, action will be taken as per the findings and recommendations of the report submitted by the committee formed by the DC office on the very night of the clash at Borhanuddin upazila.
At least four people were killed and more than a hundred others sustained injuries when religious zealots swooped on police, who had taken shelter inside a mosque in Borhanuddin following a hate conversation spread through Facebook and its messenger.
It should be mentioned that the hate conversation was spread after a facebook account of a Hindu youth named Biplob Kumer Baidya was claimed to have been hacked by unidentified miscreants.
Following the incident, local administration imposed a ban on rallies and meetings across the district until further notice to avert any untoward incident.
Apart from the committee formed by the Bhola district administration, another committee formed by Barishal Range Police is also investigating the incident. The committee is scheduled to submit its report within seven working days.
Earlier, police detained Biplab and two other Muslim youths in connection with the hate conversation. Besides, officials at the Home Ministry said the hacker of the facebook account of Biplob has been identified with the help of the US, FBI.
