We study the three-body charmed baryonic decays B{sup 0}{yields}{sigma}{sub c}{sup ++}p{pi}{sup -} and B{sup 0}{yields}{sigma}{sub c}{sup 0}p{pi}{sup +} in the four-body final state B{sup 0}{yields}{lambda}{sub c}{sup +}p{pi}{sup +}{pi}{sup -}, using a data sample of 357 fb{sup -1} accumulated at the {upsilon}(4S) resonance with the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider. We measure the branching fractions B(B{sup 0}{yields}{sigma}{sub c}(2455){sup ++}p{pi}{sup -})=(2.1{+-}0.2{+-}0.3{+-}0.5)x10{sup -4}, B(B{sup 0}{yields}{sigma}{sub c}(2455){sup 0}p{pi}{sup +})=(1.4{+-}0.2{+-}0.2{+-}0.4)x10{sup -4} and B(B{sup 0}{yields}{sigma}{sub c}(2520){sup ++}p{pi}{sup -})=(1.2{+-}0.1{+-}0.2{+-}0.3)x10{sup -4} with signal significances of 13.1{sigma}, 9.4{sigma} and 7.1{sigma}, respectively. The errors are statistical, systematic, and due to the uncertainty in B({lambda}{sub c}{sup +}{yields}pK{sup -}{pi}{sup +}), respectively. We also set an upper limit B(B{sup 0}{yields}{sigma}{sub c}(2520){sup 0}p{pi}{sup +})<0.38x10{sup -4} at the 90% confidence level. In addition, we obtain a nonresonant branching fraction of (6.4{+-}0.4{+-}0.9{+-}1.7)x10{sup -4}, and a total branching fraction of (11.2{+-}0.5{+-}1.4{+-}2.9)x10{sup -4} for B{sup 0}{yields}{lambda}{sub c}{sup +}p{pi}{sup +}{pi}{sup -}.
