A murder case has been filed against a woman who used to work as a domestic help in the Mohammadpur flat where a woman and her daughter were found dead on Monday.

AZM Azizul Islam, husband of the deceased woman and father of the girl, filed the case with Mohammadpur Police Station against their domestic aide Aysha.

The accused has not been arrested yet.

Assistant Commissioner (Mohammadpur Zone) of DMP's Tejgaon Division Abdullah Al Mamun said an investigation is underway over the murder of Layla Afroz, 48, and her daughter Nafisa Binte Aziz, 15.

According to the case statement, the accused, Ayesha, started working as a part-time domestic help at the flat four days earlier.

Azizul Islam said he found his wife dead with multiple cut injuries and his daughter critically injured when he returned home around 11am on Monday.

His daughter was taken to Shaheed Suhrawardy Medical College Hospital where she was declared dead.

The complainant said CCTV footage showed the accused entering the flat at 7:51am and leaving around 9:35am with valuables, leading him to believe she killed the two during that period.
