The home of a wealthy businessman living in the same street as Liverpool football manager Kenny Dalglish was the target of two shootings, a court has heard.
John Ball hired a security guard to keep watch on his home in Southport, Merseyside, following the attacks in March and June 2009, Woolwich Crown Court was told.
He is also believed to have been the target of a failed grenade attack on July 26 2009.
But the device was left on Mr Dalglish's wall by one of two men who ran off when police officers arrived at the scene, the court heard.
Tony Downes, 25, and Kirk Bradley, 26, are allegedly linked to the attack, which was part of a two-year campaign of terror against the people of Liverpool.
They are being tried in their absence after escaping from a prison van while travelling to a trial for the attacks at Liverpool Crown Court last July.
Downes, of no fixed address, and Bradley, of Altfinch Close, Stockbridge Village, Liverpool, deny charges of conspiracy to possess firearms with intent to endanger life and conspiracy to damage property with intent to endanger life.
Colin Fitzgibbon, 41, of West Oakhill Park, Old Swan, Liverpool, denies a charge of conspiracy to possess firearms with intent to endanger life.
Security guard Gary Ballard told the court he was watching Mr Ball's home at about 9pm on July 26 when he saw three men pull up behind him in a Lexus car.
He said: "Two of the men walked down the road and one put his hood up after glancing at me. They were looking a bit shifty."
