Vandals attacked the Edinburgh home of Sir Fred Goodwin, the retired chief executive of Royal Bank of Scotland Group PLC.
Police officers were stationed outside the villa after the attack. Edinburgh officials said vandals broke front windows at the home Wednesday and wrecked a side and back window of Goodwin's black Mercedes, which was parked in the driveway.
The Edinburgh Evening News received e-mails from a group claiming responsibility.
Goodwin, who retired in October, has come under fire in recent weeks for refusing to give up a pension package after overseeing a period of rapid expansion at Royal Bank that culminated in its near-collapse last year.
Police officials said they were investigating the attack. No one was injured in the attack, officials said, and Goodwin was not home at the time. A spokesman for Goodwin would not discuss the incident.
