Accusing SAD-BJP Government for its patronage to the Sand Mafia in Punjab, Aam Aadmi Party (AAP) today said that with the recent allocation of 90 sand mines in state to their favourites till the year 2021, SAD-BJP leader stands exposed on their nexus with Sand Mafia.Co-Convener of AAP’s RTI Wing, Dinesh Chadha today revealed the documents obtained under RTI Act to authenticate his allegations and said that recently SAD-BJP government auctioned 90 mines, which were awarded to their favourites for next five years till 2021, contrary to the policy, which allows allocation of mines only for three years.As SAD-BJP leaders have already smelled their humiliating defeat in the upcoming assembly elections, thus they violated the mining policy in the greed of continuing their control on the sand mafia even after losing the poll, Chadha alleged.Unveiling the detail of the mines, which were auctioned, Chadha said out of total 90 mines, 19 are in Hoshiarpur, three in Jalandhar, Six in Ludhiana, 12 in Mohali, 15 in Pathankot, six in Gurdaspur, two in Moga and four in Patiala district.While the people of Punjab were finding it hard to construct their own dwelling unit due to sky-high prices of building material, SAD-BJP leaders were busy to dig out their “Gold mine” through sand Mafia, Chadha alleged.Once voted to power, AAP would re-investigate all such bungling in Mining Department and illegal allotments of mines would be cancelled and given to the unemployed youth, Chadha said.
