Two persons, including a medical student, were on Monday questioned by police in connection with the Jaipur serial blasts, official sources said.
Police summoned them on the basis of clues provided by some of those arrested for alleged involvement in the Ahmedabad explosions, they said.
"We are broadly questioning these people about their links and their involvement, direct or indirect in bomb blasts in Jaipur and other places," the sources said.
They declined to give any further information saying that at the moment 'we are not in a position to divulge anything more to media as it will affect our investigation'.
