Police hunting vandals who attacked the plush home of controversial former bank boss Sir Fred Goodwin have received emails warning more bankers will be targeted.

Windows were smashed at the ex-RBS chief executive's multi-million pound villa in the upmarket Morningside area of Edinburgh, while a Mercedes S600 car parked in the driveway was damaged.

A statement issued to Scottish media organisations shortly after the attack said: "We are angry that rich people, like him, are paying themselves a huge amount of money, and living in luxury, while ordinary people are made unemployed, destitute and homeless.

"This is a crime. Bank bosses should be jailed. This is just the beginning."

Lothian and Borders Police have received emails warnings of further attacks on bankers.

A spokesman said: "We are aware that an organisation claiming to be responsible for the vandalism had made contact with media outlets and this also forms part of our inquiry.

"The force takes very seriously any planned attack on any individual or their property.

"We have been in contact with the owner of the property, who was not in the house at the time, and can confirm no one was injured."

Sir Fred has not been seen in public since the row over his pension escalated. According to reports, he removed his two children out of school due to fears for their safety and the family is now thought to be temporarily living abroad.

Sir Fred is at the centre a row about his £700,000-a-year pension from RBS which was rescued from collapse by a taxpayer bail-out.

He rejected Government pressure to accept a reduction in his package, insisting that changes to the early retirement deal he negotiated when he was forced out in the autumn were "not warranted".

The massive payout was branded "obscene" and "grotesque" by MPs and "unjustifiable and unacceptable" by Prime Minister Gordon Brown.

Earlier this month, Labour deputy leader Harriet Harman said the Government was taking "all steps" to challenge the enforceability of his pension contract.

Asked if the Prime Minister had sympathy for Sir Fred, a No 10 spokesman said: "On the specific question of damage to his property, there can be no excuse for people breaking the law."

Dubbed "Fred the Shred" for his ruthless cost-cutting, Sir Fred boasted of catapulting RBS "to the top of the premier league" with a £49 billion deal to capture Dutch rival ABN Amro in 2007.

But the acquisition proved disastrous for RBS as the credit crunch gripped markets - exposing the bank's weak balance sheet and bringing the firm to the brink of collapse.

RBS is now nearly 70 per cent owned by the taxpayer after a £20 billion bail-out.

Last month the bank unveiled a record £24.1 billion loss and plans to raise up to £25.5 billion from the taxpayer.
