An 11-year-old girl went missing from the capital's Mohammadpur area on Sunday evening.

Arabi Islam Suba, a class-6 student at a school in Barishal, came to the city with her family for the treatment of her mother, who is battling lung cancer.

Suba's family started living in a house in the Mohakhali area as her mother initially received treatment at a private hospital in Gulshan, said Suba's uncle Maidul Rakib.

Recently, her mother's chemotherapy began at the National Institute of Cancer Research & Hospital, and four days ago, she along with Suba moved to her sister-in-law's home near Krishi Market in Mohammadpur.

Suba left the home around 6:00pm on Sunday with her younger cousin. While crossing the road near Prince Bazar in the Krishi Market area, her cousin moved ahead after passing a vehicle and reached home, but Suba did not, Maidul said.

The family immediately searched the surrounding area but could not find her. Later, they filed a general diary with Mohammadpur Police Station.

Hafizur Rahman, inspector (investigation) of the station, said they have engaged multiple teams to trace the girl.
