A young mother and her two daughters were found dead at their government staff-quarters residence in the capital's Darus Salam area on Monday evening.
The deceased were identified as Jasmine Akhter, 35, wife of Md Hasibul Islam, and their daughters Asifa, 9, and Abila, 5.
Hasibul is an assistant legislative draft-man while Jasmine used to work at Khamar Bari.
Assistant Commissioner (Darus Salam) of Dhaka Metropolitan Police Jahangir Alam said Hasibul claimed that he along with one of his relatives found their 3rd floor apartment at Tularbagh near Govt Bangla College locked from inside in the evening, reports UNB.
They broke open the door only to find the trio lying in a pool of blood, he said quoting Hasibul.
There were marks of sharp weapons in the necks of the two children and in the neck and abdomen of Jasmine, Jahangir said, adding that Jasmine might have committed suicide after killing the two daughters.
He, however, said the mystery will get unveiled only after investigation.
