German prosecutors raid 86 properties across Europe in insider trader probe Thursday's raids centred on suspicions of stock fraud, market manipulation, breach of trust and insider trading, according to the prosecutors. Authorities raided 53 addresses in Germany and asked colleagues abroad to target a further 29 sites in Europe and four outside the region. The prosecutors have gained a reputation for fighting penny stock frauds, a position strengthened by this year's successful convictions. The spokesman reportedly said: "It's easier to influence the shares prices of small companies this way. It would be much more difficult to do it with the stock of huge corporations.
