The youth wing of the MNF today staged a protest outside the residence of Mizoram Chief Minister Lal Thanhawla demanding explanation from PWD Minister Lalthanzara on the collapse of a bridge in February this year.

One person had lost his life in the incident and another was critically injured.

The MNF had also issued an ultimatum earlier this month the PWD minister to explain the reasons that led to the collapse of the bridge.
