Gazipur: A helicopter landed in a restricted area at Kashimpur Central Jail in Gazipur and dropped four passengers there on Thursday morning.

The copter landed on the prison school field at the jail at about 11:00am. After leaving four passengers, the chopper whirled away.

However, the jail authorities held the four passengers and took them for interrogation.

The jail directorate Inspector General (IC) Prison Mohammad Mamun told NTV Online said the detainees are a Bangladeshi, a Malaysian, and two children.

Meghna Group is the owner of the helicopter while pilot of the chopper was Wing Commander (Rtd) Sohel Latif.

Kashimpur High Security Central Jail jailer Bikash Raihan told NTV Online a rented helicopter landed in the jail premises at about 11:00am. The four passengers are a Bangladeshi man, his Malaysian wife and their two children.

During primary interrogation, the Bangladeshi, Billal Hossain, said he was going to attend a wedding ceremony at Kashimpur along with his family.

Bikash Raihand said the detainees claimed the helicopter was supposed to land on a factory near the central jail but it mistakenly landed inside the jail properties.

Further action will be taken against the passengers after discussing the issue with higher authorities, said the jailer.
