We study analytically the asymptotic behaviour of the average probability for the trajectory of a 2D Brownian particle wandering in the presence of randomly distributed traps to wind n times around a given point after a time t. It is shown that with , where the first exponent represents a well known long-time tail of the probability that a particle will not be trapped.
