21 contractors who had participated in the bidding procedures for 15 lots of the
project for the construction of Incheon urban railroad line 2 were found to have
colluded in bidding by selecting successful bidders and acting as sham bidders, and
the KFTC imposed fine of 132 billion 200 million won against them, along with an
order to take corrective remedies, and filed a criminal complaint with the
prosecution against 15 corporations involved in the case.
