Star-shredding supermassive black holes (Tidal Disruption Events, TDEs) are potential emitters of high energy hadrons and neutrinos. Several TDEs have been observed as coincident with neutrino events detected at the IceCube neutrino observatory. I will review these recent multimessenger observations, and present models of neutrino emission in TDEs that successfully interpret the data. Emphasis will be on the hypothesis of a direct connection between the neutrino emission and the observed infrared dust echoes of the candidate TDEs. Broader implications will be discussed at the end.
