Figure 1: Overlay showing the positions of the various components described in the text. The optical image (kindly provided by D. Malin) shows the well-known dust lane of Centaurus A and the faint diffuse optical emission that extends to very large radius. The white contours denote the radio continuum emission (after Morganti et al. 1999) showing the bright inner radio lobes and the large-scale jet that connects these lobes to the so-called Northern Middle Lobe (NML) in the top-left of the figure. The black contours denote the H  I cloud discussed in this paper (see also Fig. 2). The locations of the inner and outer filaments of highly ionised gas are indicated, as well as the location of young stars (see also Fig. 4).

	Figure 2: Total HI intensity image of the NE H  I cloud. The locations of the two position-velocity plots of Fig. 3 are indicated. Contour levels are 1, 3, 5, 7, 9, 11, 13,  cm-2.

Figure 4: H  I contours of the southern region of the H  I cloud, drawn on top of a broad band optical image (kindly provided by M. Rejkuba). The hatched area indicates the location where the anomalous H  I velocities are detected while the arrow indicates the location and the flow direction of the radio jet. The filament of ionised gas is visible in the top left. The dashed lines roughly indicate the locations of young stars. Contour levels are as in Fig. 2.
