N2 - We investigate the Lévy flights observed experimentally in the transport of tracers in a temporally irregular flow that has no Kolmogorov-Arnold-Moser surfaces, and show that the Lévy flights are due to the sticking of the tracers near the walls. The tracer is found to spread superdiffusively with an exponent v = 3/2, in reasonable agreement with the experiments.
