A senior police officer told PTI that the Belgian-born economist, now an Indian citizen, was addressing a meeting in Garhwa district in violation of the Model Code of Conduct.
"Dreze was taken into preventive custody for addressing a meeting at Bishanpura in Garwha district, about which the local administration had no information," he said.
