Allies made one change to the starting XI that lost 1-0 at Berekum Chelsea after Mohammed Zakari replaced Paul Abanga.
Kingsley Braye produced the first moment of quality on 14 minutes when his in-swinging shot was saved by the Olympics goalkeeper.
Another opportunity followed soon after, this time for Nafiu Sulemana, who spun on an incisive ball from Richmond Lamptey and dispatched a shot that was claimed again by the shot-stopper.
Olympics took the lead through Maxwell Nii Abbey in the 9th minute after Desmond Abanga was adjudged to have committed a foul in the 18-yard box.
Both sides squandered several goal scoring opportunities.
Olympics continued to press forward and in one of those powerful drive, the ball struck the hand of substitute Ernest Adu -leaving referee Musah Mubarik with no choice but to award a second penalty to the home side.
Again, Maxwell Nii Abbey elected himself and displaced goalkeeper Rashid Seidu to make it 2-0 with 10 minutes left on the clock.
The result takes Olympics back into the top four after nine matches while Inter Allies continue to stay in the drop zone.
