  We construct here a class of collapsing scalar field models with a non-zero
potential, which result in a naked singularity as collapse end state. The weak
energy condition is satisfied by the collapsing configuration. It is shown that
physically it is the rate of collapse that governs either the black hole or
naked singularity formation as the final state for the dynamical evolution. It
is seen that the cosmic censorship is violated in dynamical scalar field
collapse.
