We have grown all-too-accustomed to predators trying to grab assets from UK investors on the cheap but the rapacity has hit new depths.

Insurance company Aviva is warning its small investors of a barefaced attempt to persuade them to sell their shares at significantly less than market value.

A company called Litani LLC has sent documents to thousands of small investors. The paperwork specifies that it is offering to buy shares at much less than they are worth.

Presumably it is hoping people will be taken in by the documents’ official appearance and will not read or understand them properly.

It is shocking in its audacity. What is even more shocking is that no-one has been able to stop such an arrant rip-off.
