Six Brits and five Australians appeared in court today accused of running a boiler room gang that targeted elderly victims.

The scammers allegedly worked from a sprawling mansion on the outskirts of Bangkok where they cold-called residents in Australia - fleecing them of their life savings.

They allegedly scammed them out of more than two million AUD before police raided the property on Monday morning.

Footage shows the group, which also included a South African and a Canadian, being frogmarched from the police headquarters into waiting vans to be taken to court this morning.

Lieutenant Colonel Warat Soemsujari from the Crime Suppression Division (CSD) said the suspects have been charged with 'jointly being a member of a group of persons who conceal the manner of operation and with the intent to act illegally or illegally, being an alien who has been granted temporary residency in the Kingdom, engaged in employment or employment without a permit, and being an alien working without a work permit.'

Police named the arrested men as Brett Peter Dawson, 51, Nicholas John Mason, 43, Mark Dennis, 54, Christopher Pepena, 48, and Luke Cameron Campbell, 45, all from Australia.

While the British suspects were Lewis Samuel Gillespie, 30, Ellis Ian James, 59, Mark Mackenzie, 61, Dean Crowley, 42, Mark Andrew Howship, 56, and Lewis Robbie, 40, all of them from the United Kingdom.

Police also arrested Jeremy Fortoen, 44, from South Africa and Szeto Kwok Chi, 58, from Canada.

Officers said that the gang were living seemingly respectable lives but arrived at the call centre every day to target new victims, tricking in them into locking up their cash in bonds with annual yields of up to 10 per cent.

Armed cops raided the luxury villa in Samut Prakan where they found 58 computers and notebooks. There were also several clocks on the wall showing different time zones across Australia.

Police also recovered scripts that the fraudsters would read to victims to lure them into investing in bonds with annual yields of between seven and ten per cent, with maturity times of between one and three years.

There were allegedly records of more than 14,000 Australian nationals who had been targeted.

Officers said that at the property, a large curtain would cover the entrance where the gang members parked their cars each day. The working hours were 9 am to 6 pm Sydney time.

Officers monitored the activity at the property for several months and found that those involved were all living seemingly normal lives in the country, but they would work at the call centre during the daytime and leave at night.

Kristie Lee Cressy, Senior Officer at the Australian Federal Police (AFP), said: 'AFP's investigative unit received intelligence about a sophisticated call centre syndicate that had relocated its operations to Thailand. We shared this information with the Royal Thai Police.

'Following a joint investigation with Thai authorities, a search warrant was obtained and a raid was carried out at the premises.

'This syndicate was specifically targeting Australian victims, scamming them through elaborate schemes. The total losses caused by their operations amounted to nearly two million Australian dollars, money stolen from hardworking Australians.

'This operation marks a significant success in the ongoing cooperation between the Thai and Australian police.'
