The fast bowler surrendered to the court on Oct 5, a day after police arrested his wife Jesmin Jahan.
On Thursday, the court of Dhaka Metropolitan Magistrate Yousuf Hossain rejected Shahadat's bail plea and granted the law enforcers three days for interrogating him.
In September, the cricketer filed a police complaint claiming his house help had gone missing.
But several hours later, the 11-year-old girl surfaced to accuse the cricketer and his wife of regular torture.
Police said one Khandkar Mozzamel Haque found the girl at Mirpur and took her to the local police.
Haque later filed the case.
Hossain last played for Bangladesh in May against Pakistan. He went off the field on the first day of first Test with a leg injury.
The Bangladesh Cricket Board (BCB) got him treated in Australia and he was undergoing a rehabilitation programme.
The BCB had said that the reports of torturing a minor was ‘utterly embarrassing’ and banned the pacer from all forms of cricket until the charges were settled.
