Okolle, who played a key role in Churchill's attack, then scored twice. He was brought down by Vasco's Sujay inside the box and referee Angelo Fernandes awarded a penalty, which he converted in the 40th minute.
Soon after resumption in the second half, Okolle completed a brace, scoring from the top of the box, off a pass from L Robert.
