"We don't know anything, we just want our daughter back," said a tearful Marium Begum, mother of teenage domestic help Chandni Khatun Jui, urging the authorities concerned to find out the mystery behind her daughter's landing in a shelter home.

Jui's parents Dulal Miah and Marium Begum of Khochabari village in Sadar upazila are crying to get back their daughter but they don't know how.

Six years ago, when Jui was only nine years old, her parents engaged her as a house help at the house of Nazrul Islam, the then Lalmonirhat District Jail superintendent, now serving as superintendent at Nilphamari District Jail.

But, nearly two weeks ago, suddenly the poor couple found their teenage daughter at a shelter home in Rangpur city instead of

Nazrul's house.

"Due to acute hardship we sent Jui to Nazrul's house to work as a domestic help. During that time the jail super promised us that he would bear all expenditure of Jui's marriage when she is old enough,” Marium said.

"But since then, Nazrul and his family members didn't allow our daughter to visit us or even talk to us over mobile phone," she said, adding that the jail super took our daughter from our home and we want her back now.

"At one stage we sensed that something wrong happened to our daughter," Jui's father Dulal said, adding, "Nazrul was plotting conspiracy against our daughter and seemed reluctant to return her to us."

On September 22, Nazrul phoned us and said that Jui fled from his house, which seemed quite unusual, Dulal said.

"We submitted a complaint to a Lalmonirhat court in this regard on September 24. The court issued a search warrant against three people, including Jail Super Nazrul, the same day," he said, adding that Nazrul is now threatening him for taking the legal step in this regard.

Jail Superintendent Nazrul Islam said Jui fled from his house at Babukha in Rangpur city around 4:00am on September 22.

Three days later, Rangpur Metropolitan Police rescued her and sent her to a shelter home run by the Social Welfare Departmentthesameday.

He, however, could not give any satisfactory answer when this correspondent asked him why Jui fled from his house.

Officer-in-Charge of Kotwali Police Station Rezaul Karim said they rescued Jui on September 25 and sent her to the shelter home as nobody then came forward to take her responsibility.
