Hossain, who has played 38 Tests and 51 one-day internationals for Bangladesh, went into hiding after police sought the cricketer and his wife's arrest for allegedly torturing the girl employed as a maid in their house.
The cricketer was suspended from all forms of the game by Bangladesh Cricket Board (BCB) on September 13 after a case was registered against him under the Women and Children Repression Prevention Act.
When she was taken to a local police station, she accused the cricketer and his wife of regular torture.
Police said that one of her hands had been burnt with a hot cooking paddle, while other injury marks were also found on her body.
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 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.
