Members of Rapid Action Battalion (Rab) have arrested the key suspect in a case filed over the murder of a woman and her son in Chandgaon of Chattogram city.
Md Faruk (33), a vegetable vendor, was held from the port city's Pakkar Matha area on Thursday, said Lt Col Moshiur Rahman Jewel, commanding officer (CO) of Rab-7.
On August 24, police recovered the bodies of one Gulnahar and her eight-year-old son Rifat from their house in Chadgaon's Pathania Goda area.
Both had wounds inflicted by sharp weapon. During interrogation, Faruk said he plotted the double murder after watching a crime show on TV, the CO said.
"Faruk was a paying guest at Gulnahar's house and he sold food items prepared by her on the streets. A rift developed between the two over money," Lt Col Moshiur said.
Faruk killed Gulnahar and murdered her son because he was a witness, the Rab official said quoting Faruk.
"Faruk threw his blood-stained clothes in a drain and left the city. He also switched off his phone. In interrogation, Faruk said he learned this from a TV serial," Moshiur added
Faruk went to Khagrachhari and remained in hiding for a few days. He then moved to Dhaka before returning to the port city again, the Rab official added.
After the incident Gulnahar's daughter filed a case with Chandgaon Police Station accusing Faruk.
