Regarding attachment of property in customs case. Can father be jailed

My father was involved in a customs case in 2012. The property we live in is in my grand- moms name but was in my father's name when it was bought and transferred in 1998. My dad was imposed with sections 112,112a,114aa,117 of the customs act. My grand- mom is alive. Can the customs attach the above property is there even a slightest chance ? A penalty of 60 lacs was imposed and an appeal has been filed in the tribunal . Can the govt charge interest on the penalty before the judgement of the appeal? Can my dad be imprisoned for this?
