  The cross section for the reaction $ e p \to e^{\prime} p \pi^{+} \pi^{-}$
was measured in the resonance region for 1.4$<$W$<$2.1 GeV and 0.5$<Q^{2}<$1.5
GeV$^{2}$/c$^{2}$ using the CLAS detector at Jefferson Laboratory. The data
shows resonant structures not visible in previous experiments. The comparison
of our data to a phenomenological prediction using available information on
$N^{*}$ and $\Delta$ states shows an evident discrepancy. A better description
of the data is obtained either by a sizeable change of the properties of the
$P_{13}$(1720) resonance or by introducing a new baryon state, not reported in
published analyses.
