  We investigate the dynamical evolution of entanglement entropy in a
holographic superconductor model by quenching the source term of the dual
charged scalar operator. By access to the full background geometry, the
holographic entanglement entropy is calculated for a strip geometry at the AdS
boundary. It is found that the entanglement entropy exhibits a robust
non-monotonic behaviour in time, independent of the strength of Gaussian quench
and the size of the strip: it first displays a small dip, then grows linearly,
and finally saturates. In particular, the linear growth velocity of the
entanglement entropy has an upper bound for strip with large width; The
equilibrium value of the non-local probe at late time shows a power law scaling
behaviour with respect to the quench strength; Moreover, the entanglement
entropy can uncover the dynamical transition at certain critical quench
strength which happens to coincide with the one obtained form the dynamical
evolution of scalar order parameter.
