Michelle reveals how one property owner is brought to justice after managing to get his hands on not one, not two, but three social housing properties in three different council areas. Croydon Council launches an investigation into the tenant and the full scale of the fraud begins to emerge. Housing officers discover the tenant was also the part-owner of two other properties.

Meanwhile, in Lincolnshire housing officers finally get their hands on the keys to a three-bedroom house that's been lying empty for more than a year. And in Aylesbury, noise complaints prompt a father to give back the keys to a property he's no longer living in and his teenage son has been using.

Tensions run high as investigators race between two addresses and carry out simultaneous door knocks in a carefully planned operation. They investigate a suspected unlawful sublet and want to find out exactly who is living at each address. With the official tenants and the suspected subtenants each telling different stories, the situation becomes fraught and the police are called in.

In another case, investigators reveal how one woman applied for a council property using the identity of a baby who was born 50 years ago but who died in infancy. She is also found to have claimed more than £150,000 in benefits using the same false identity.

And Michelle reveals how one Greenwich council tenant was actually living hundreds of miles away in Norway. Investigators trick the tenant into coming back to the UK so they can confront him. The council property is searched, the tenant is arrested and charged with fraud by false representation.
