AN increase in prostitution and sex trafficking is expected in the run up to the 2012 Olympics.

A report by the Metropolitan Police Authority (MPA) warned the increase in would put women at risk.

It has also reported a small increase already in the number of trafficked women working in the five Olympic host boroughs, including Waltham Forest.

Vistors, athletes and workers at the Stratford site are expected to fuel the sex industry boom.

During the Athens Games, sex trafficking almost doubled.
