Dhaka: An Air Force helicopter on a training flight crashed on October 19 in South Eastern Bangladesh killing all four people on board, Defence Ministry officials said.

The Soviet-made MI-17 chopper, which took off from its base in the port city of Chittagong, went down about 16:30 hours (local time) in Ukhiya, some 300 km from Dhaka, near the Myanmar border, a Defence official said.

He said that an investigation had been ordered into the crash but could not give any other details.

A media report said that the crash occurred after the helicopter hit a local television tower.
