An extension of the Parikh-Wilczek's semi-classical quantum tunneling method, the tunneling radiation of the charged particle from a charged BTZ black hole was investigated. Difference from the uncharged mass-less particle, the geodesics of the charged massive particle tunneling from the black hole is not light-like, but determined by the phase velocity. The derived result shows that the tunneling rate depends on the emitted particle's energy and electric charge, and takes the same functional form as uncharged particle. It also prove that the exact emission spectrum is not strictly pure thermal, but is consistent with the underlying unitary theory. (c) 2006 Elsevier B.V. All rights reserved.
