LONDON (Reuters) - Two people have been arrested in London on suspicion of insider trading after investigators raided two addresses in the UK and one in Germany, Britain's top financial regulator said yesterday.

The Financial Services Authority (FSA) said that a 37-year-old professional man and a 28-year-old woman had been arrested after the joint operation with the police and prosecuting authority in the central German state of Hesse.

"No further details can be confirmed at this time," the FSA said in a brief statement. "The arrests are not linked to any other ongoing insider dealing investigation."

The Frankfurt prosecutor's office declined to comment.

The man, who was authorised by the FSA, is likely to have been working in the financial services sector and have been aware of the relevant laws and regulations governing insider dealing, one source familiar with the arrests said. The raids, in the early hours of yesterday, were carried out in London and in Koenigstein, near Frankfurt.
