Abstract Let G=(V 1, V 2; E) be a bipartite graph with| V 1|=| V 2|≥ 3 k, where k is a positive integer. We prove that if the minimum degree of G is at least 2 k+ 1, then G admits k vertex-disjoint cycles such that each of them has at least two chords. This is a bipartite counterpart of the result due to P. Balister, H. Li and R. Schelp.
