  The Einstein Gauss-Bonnet theory of gravity is the low energy limit of
heterotic super-symmetric string theory. This paper deals gravitational
collapse of perfect fluid in Einstein Gauss-Bonnet gravity by considering the
Lemaitre - Tolman - Bondi metric. For this purpose, the closed form of exact
solution of equations of motion has been determined by using the conservation
of stress-energy tensor and the condition of marginally bound shells. It has
been investigated that the presence of Gauss-Bonnet coupling term $\alpha>0$
and pressure of the fluid modifies the structure and time formation of
singularity. In this analysis singularity form earlier than horizon, so end
state of the collapse is a naked singularity depending on the initial data. But
this singularity is weak and timelike that goes against the investigation of
general relativity.
