An elderly woman, 72, was arrested in Bulgaria in a raid against financial fraudsters.
The woman was seized during an operation in the Bulgarian cities of Stara Zagora and Varna, targeting a ring for tax siphoning.
Four people were attested during the operation.
The head of the crime ring is believed to be one of the detainees - a man aged 44.
They had siphoned value added tax (VAT) worth about BGN 15 M, media say.
Just several days ago Bulgaria uncovered another group suspected of major financial frauds. The police arrested 13 Bulgarians on suspicion that since late 2005 they had siphoned VAT worth BGN 1 M (about EUR 500 000) every month.
