An infinite dimensional extension of the spin 1 Galilean conformal algebra in the plane is investigated. We present the coadjoint representation and a classification of all possible central extensions. Furthermore, we study representations of the algebra with central extensions. Kac determinant for the highest weight Verma modules is given explicitly which shows that the Verma modules are irreducible for nonvanishing highest weights. A boson realization corresponding to unit central charge is also presented.
