Whatever you do, dont open your door to this gang of travellers.
They are suspected of conning the elderly and vulnerable out of £3million and have been named as some of the UKs most wanted fraudsters.
The gang of five men and one woman are wanted after disappearing while out on bail.
Police have now launched an appeal for any information related to the rogue traders and conmen, who have been tricking residents into agreeing to unnecessary work on their homes which was never carried out.
In some instances, the fraudsters pretended to be judges, police and trading standards officers to make their victims transfer large sums of money.
The leaders of the gang have been identified as husband and wife Kathleen McCarthy, 29, and Oliver Boswell, 30, who are said to be living in Wolverhampton.
The pair have already been convicted of money laundering, with McCarthy stealing more than £220,000 from 14 elderly victims in just one year.
But they are now on the run after failing to turn up for their trial at Lewes Crown Court in December.
Other members of the gang include James Flynn, 42, who duped a man in west London into transferring £64,400, John McCarthy, 33, who is wanted for five fraud and money laundering offences after posing as a trading standards officer, John OBrien, 49, from Cambridge, and Daniel Sheridan, 48, from Wolverhampton.
OBrien allegedly made a victim hand over £75,000 in an advance fee scam where they are convinced to make an up-front payment in the promise of getting a share of a larger sum later.
Sheridan is accused of posing as a judge during a phone call and threatening a victim with jail for contempt of court unless he handed over £79,000.
The Joint Fraud Taskforce, made up of police, banks and other industry bodies, issued the appeal.
They are also appealing for information about two other suspected fraudsters: Nathan Hudson, 34, and Denis Marku, 21.
Hudson, from East Yorkshire, is suspected of stealing £110,000 from people who invested in several fake businesses.
Marku, from London, is suspected of using his role as a cashier at a Chelsea bank to steal more than £3million from customer accounts.
Commissioner Ian Dyson, from City of London Police, added: I would urge anyone who has information on the wanted fraudsters to call officers as these people will continue to commit fraud across the globe that cause misery to so many worldwide.
