Four people who were found slaughtered in a paddy field of Baladighi village in Shibganj upazila on May 7 have been murdered over the share of money got from selling drugs, claimed police on Monday.
Police arrested three people who were directly involved in the four murders, said district police super Ali Ashraf Bhuiyan in a briefing.
The arrestees were identified as Jewel Sheikh, 25, son of Rafiqul Sheikh of Chawkpara village in Shibganj upazila, Abul Kalam Azad, 48, son of Abdus Samad of Talukdarpara of Chandanpur, and Rubel Miah, son of Abu Bakar of Daboir village.
Meanwhile, Rapid Action Battalion (Rab) members arrested two more suspects over the murders.
They are M Abu Bakkar Pramanik, 50, son of Rostam Ali of Badladighi village, and M Zahidul Islam alias Tera, 48, son of late Abdus Sattar of Kathpara. They were later handed over to Shibganj Police Station.
Earlier on May 7, four young men Zakaria Islam, 32, son of Jahurul Islam of Kathgara village in Shibganj, Shabrul Islam, 35, son of Asir Uddin of Kathgara Chawkpara, and Helal Uddin, 36, son of Azahar Ali of Punot village in Kalai upazila of Joypurhat and Khabir -- were found slaughtered in a paddy field of Baladighi village in Shibganj upazila.
The SP said police arrested Jewel, Azad and Rubel on Sunday night and they were directly involved in the murders.
He said the arrestees revealed that a total of nine people were involved in the killings that were committed over the share of money.
Jewel Sheikh planned the murders as he owned deceased Zakaria Islam Tk 6,000.
On the night of May 7, Jewel called Zakaria and asked him to take his money and bring Shabrul Islam along with him.
However, they were killed while going to bring the money, said SP said.
Jewel slaughtered Zakaria and Shabrul was slaughtered by another one while two others -- Helal and Khabir -- accidentally witnessed the crime.
Later, they were also slaughtered so that there remained no evidence.
Helal and Khabir were also involved in drug business and they were killed on their way to Dhaka for selling drugs, Ashraf said.
