Law enforcers are yet to identify the motive and persons responsible for murdering a mother and her two children who were found hacked to death in their fifth-floor residence in Khotiber Haat area in Chittagong on Tuesday night.
The deceased are Doly Akhter, 30, wife of expatriate Anwar Hossain, and her son Albhi Ibn Anwar, 10, and daughter Adiba Payel, 6.
Police said they were looking for an unidentified male tutor who used to come to the residence every day around the time the murder occurred.
The footprint of a male person, presumably the killer's, was found on the bloodstains in the house. Police also recovered a knife and a cleaver from the house, said police.
Five people -- the building's gatekeeper Abul Hossain, Doly's friend Shila and Shila's mother, and Doly's friend Mukta and Mukta's niece Irin -- have been interrogated by police.
Meanwhile, Anwar, reaching Bangladesh yesterday morning, told police that he found Doly's cellphone switched off from Tuesday afternoon.
Doly's father Md Ihsaq filed a case with Panchlaish Police Station yesterday accusing unidentified persons.
