British prosecutors say police found a dossier labeled "Plan A" in the home of a suspect accused of plotting a terrorist attack.

Erol Incedal is charged with preparing a terrorist act and possessing bomb-making instructions. He denies the charges.

Prosecutors say the 26-year-old Incedal may have been planning indiscriminate Mumbai-style shootings or to attack a "significant" individual. The address of former Prime Minister Tony Blair was found in his car.

Prosecutor Richard Whittam said Wednesday that police found a document headed "Plan A" in Incedal's home after he was arrested in October 2013.

?It listed "three to four workers, two tennis (rackets), one month's surveillance, rent nearby flat, transport, assess security, assess risk, legitimacy, action etc."

Some parts of the trial are being held in secret on national security grounds.
