Mohammad Siddikur of Bangladesh shot a second consecutive 6-under-par 66 for a two-shot clubhouse lead in the Indian Open as the second round ended early because of bad light on Friday.
The premature end left 26 players still to finish the round in the Asian Tour event.
Siddikur, who shot a bogey-free first round to share the lead with five others, eagled the par-5 first hole before bogeying twice and rebounding with six birdies.
He was at 12 under overall, two strokes ahead of Chapchai Nirat, who shot a 68.
Angelo Que of (68) and Shiv Chowrasia (68) were tied for third at 7 under. However, Adam Groom and Rahil Gangjee were also in the mix at 8 under with two holes to play.
