 Observation of the decay $B^0_s\to \phi\pi^+\pi^-$ and evidence for $B^0\to \phi\pi^+\pi^-$ The first observation of the rare decay $B^0_s\to\phi\pi^+\pi^-$ and evidence for $B^0\to\phi\pi^+\pi^-$ are reported, using $pp$ collision data recorded by the LHCb detector at centre-of-mass energies $\sqrt{s} = 7$ and 8 TeV, corresponding to an integrated luminosity of $3 {\rm fb}^{-1}$.
