William Hunt alleges the incident is connected to an eight-year campaign of harassment during which he has applied for restraining orders on four occasions.

The suitmaker's shop, in London's prestigious Mayfair area, was severely damaged when a man wielding an iron bar threatened staff and sprayed red paint on displays inside the store before smashing a window.

Hunt tells Britain's The Sun newspaper, "It was a terrifying attack. This has been going on for years and I feel nothing has been done."

Robin Goodwin is due to appear at London's Southwark Crown Court next month (May15) charged with criminal damage and affray in relation to the incident.
