This paper discusses an extension of the standard model with a local symmetry of L{sub e} - L{sub {mu}} and a global symmetry of L{sub {gamma}} to incorporate a 17 keV Dirac tau neutrino. A massive neutral gauge boson (A{sub X}) and a majoron (J) are present by breaking the symmetries spontaneously. The tau neutrino, with a life-time of the order 10{sup {minus}3} s, will decay by emitting an electron and a majoron. Tau will also decay into an electron and a majoron with a branching ratio as large as 10{sup {minus}4}. The breaking scale of L{sub e} - L{sub {mu}} symmetry can be as low as 700 GeV. Hence, A{sub X} can be produced in LEP II in the near future.
