Police in West London are carrying out raids as part of a two year EU funded project to tackle human trafficking.

In 2012 the UK National Referral Mechanism received nearly 1,200 referrals of potential victims of trafficking, an increase of 25% from 2011.

BBC Radio 5 live's reporter Lesley Ashmall was given access to the police operations.
