An art collection belonging to fugitive billionaire jeweller Nirav Modi raised $8 million for Indian tax authorities when it was auctioned off on Tuesday, officials said.

Over a third of the lots up for auction — which included works by VS Gaitonde and Francis Newton Souza — sold above their higher estimate, auction house Saffronart said in a statement.

Authorities put the paintings up for sale to recover dues owed by Modi, who is accused of involvement in a massive bank fraud that rocked India’s corporate community.

Before his downfall last year, Modi owned luxury jewellery stores in several major cities across the world and boasted celebrity customers including actresses Naomi Watts, Kate Winslet and Priyanka Chopra-Jonas.

Earlier in March, Indian authorities dynamited Modi’s multi-million-dollar seafront mansion worth $14 million.
