  We point out a misleading treatment in the recent literature regarding
analytical solutions for nonminimal vector interaction for spin-one particles
in the context of the Duffin-Kemmer-Petiau (DKP) formalism. In those papers,
the authors use improperly the nonminimal vector interaction endangering in
their main conclusions. We present a few properties of the nonminimal vector
interactions and also present the correct equations to this problem. We show
that the solution can be easily found by solving Schr\"{o}dinger-like
equations. As an application of this procedure, we consider spin-one particles
in presence of a nonminimal vector linear potential.
