A narrow peak in the invariant mass distribution in a sample of B→KKSK-π+ decays collected at the KEKB asymmetric e+e- collider was reported. The sum of the observed events in the three mass bins in the signal region was found to be 56. The limited statistics and the resolution precluded a precise measurement of the width.
