The search team prowling the waters where a helicopter belonging to oil company Lukoil plunged into the sea on Thursday resulting in the death of at least three out of eight passengers have retrieved parts of the crashed chopper.

The fuselage is however yet to be retrieved while the team is still looking for one passenger feared dead after four survivors were rescued Thursday. Aviation authorities say three of the survivors are responding well to treatment while the fourth has been transferred to Accra for closer care.

It is still unclear what may have caused the accident that was detected a few hours after the crew failed to arrive at destination.
 
Meanwhile the Ghana Civil Aviation Authority (ACAA) has launched a full-scale investigation into the circumstances that led to the crash of the Ivorian registered helicopter with the registration identity as TUHAA.
 
The authority said they would not hazard any hasty suggestions as to what caused the crash until investigations were concluded.
