Etakiama scored from the spot at the death of the game after Emmanuel Ngudikama was brought down by his marker, and push the Kinshasa based club to the summit of the standings.
Earlier Guy Lusadisu had canceled Mohamed Bashir’s first half opener to set the tone for a heated finish to the game.
A spectacular performance in the late stages by the Congolese turned the game their favour, after being down for a greater part of the game.
Bashir broke the deadlock on 18 minutes, profiting from a Mudathir El-Taieb ‘Careca’ flick before firing past the AS Vita goalie, Nelson Lukong.
The homers had to wait till the 82nd minute before Lusadisu restored parity with an acrobatic shot from close range and set the stadium alive.
Few minutes later, Nizar Hamed managed to put the ball behind the back of the net, but his effort was flagged offside. The tide then turned the way of the Congolese and Ngudikama was felled in the penalty area in time added-on, before Etakiama tucked in from the spot to earn them the maximum points.
AS Vita leapt to the summit with seven points, one more than fellows TP Mazembe who were scheduled to face Egyptian giants Zamalek in the other Group A match in Alexandria.
