  We study the inflationary dynamics in a model of slow-roll inflation in
warped throat. Inflation is realized by the motion of a D-brane along the
radial direction of the throat, and at later stages instabilities develop in
the angular directions. We closely investigate both the single field potential
relevant for the slow-roll phase, and the full multi-field one including the
angular modes which becomes important at later stages. We study the main
features of the instability process, discussing its possible consequences and
identifying the vacua towards which the angular modes are driven.
