The tidal disruption of a star by a supermassive black hole provides us with a rare glimpse of these otherwise dormant beasts. It has long been predicted that the disruption will be accompanied by a thermal `flare', powered by the accretion of bound stellar debris. Several candidate disruptions have been discovered in this manner at optical, UV and X-ray wavelengths. Here I explore the observational consequences if a modest fraction of the accretion power is channeled into an ultra-relativistic outflow. I show that a relativistic jet decelerates due to its interaction with the interstellar medium at sub-parsec distances from the black hole. Synchrotron radiation from electrons accelerated by the external shocks powers a bright radio-infrared transient that peaks on a timescale ~1 yr after disruption. The, recently detected, high-energy transient Sw 1644+57 provides strong support to the presence of powerful relativistic jets during tidal disruption events. Upcoming radio transient surveys may independently discover tens to hundreds of tidal disruptions per year, complimenting searches at other wavelengths.
