  We propose a charged falling particle in an AdS space as a holographic model
of local charged quench generalizing model of arXiv:1302.5703. The quench is
followed by evolving currents and inhomogeneous distribution of chemical
potential. We derive the analytical formula describing the evolution of the
entanglement entropy. At some characteristic time after the quench, we find
that the entanglement shows a sharp dip. This effect is universal and
independent of the dimension of the system. At finite temperature
generalization of this model, we find that multiple dips and ramps appear.
