Brazilian police have arrested a German conman who claimed to have developed a scheme which he said allowed him to predict lottery numbers, transmit data and improve online banking security.
Hartmut Muller, who had been convicted of a multi-million-dollar fraud in Germany, persuaded people to invest in the scheme supposedly based on gravitational waves.
He fled to Brazil when the evidence against him began to mount.
He is expected to be extradited.
Interpol agents arrested Muller, 58, in the southern city of Florianopolis on Tuesday.
He had moved there in January, fleeing a court case in the German city of Dresden, where he and three of his partners were on trial for fraud.
Muller conned some 3,000 investors out of about five million Euros ($6.5m, £4m), the court said.
Muller had invented a pseudo-scientific theory he called “global scaling”, which he said allowed him to use gravitational waves to prevent electronic smog, use novel methods of scanning to be applied in medicine, and transmit “information without any limits in quantity, quality or time”.
The theory is of course nonsense.
