Unable to find the location of the pixel with the minimum gray level

I want to find the location of the pixel in the image which has the minimum gray level. I tried the code below. But it gives me the coordinates of more than one pixel. What I need is to find the location of one pixel that has the minimum gray level. Any suggestion would be appreciated.
minValue = min(I(:))
[row, column] = find(I == minValue);
