Arteta opened the scoring in the Premier League clash after Santi Cazorla went down after a challenge by Steven Reid, although replays showed the defender did not touch his opponent.
Victory moved Arsenal up to sixth place, two points below the top four, after a sequence of one league victory in six matches had seen them slide down the table to 10th.
