We examine the use of Laguerre-Gaussian (LG) laser beams in the tripod scheme to create the coupling between spin and orbital angular momentum in a Bose-Einstein condensate (BEC) confined by a harmonic trap. We derive and solve the Gross-Pitaevskii equation numerically to obtain the density distribution of the BEC. Orbital angular momentum from the LG beam is transferred to the BEC, inducing the formation of a giant vortex at the BEC's centre. The macroscopic flow of spinor BEC around the vortex leads to a persistent spin current in the BEC.
