Ingush police are searching for four young people suspected of
terrorist attacks, RIA Novosti cites Ingush leader Yunus-Bek Yevkurov.
Yevkurov says that the militants may have used psychotropic substances
on the young people to force them to carry out terrorist attacks.
Police believe that the terrorist attack at Domodedovo was carried out
by an Ingush native Magomed Yevloyev.
