Spanish police today said they have arrested six people suspected of involvement in a fraud totalling $600m (€452.4m) on the London stock market. The case is related to a four-year fraud investigation into Langbar, an Aim-listed cash shell which was found to have falsified its assets.

The main suspect in the fraud, which began in 2003, is among six people who were arrested in Madrid, Barcelona and the town of Elche in the southeast, Spanish police said in a statement.
