DOWNING STREET INTRUDERS SCARE.
Obadiah Marius and his girlfriend strolled into the street after wandering through a nearby Whitehall building unchallenged, a No 10 spokesman confirmed.
The incident occurred on Monday afternoon when Marius, 44, and his partner walked into 70 Whitehall, which houses the Cabinet Office, off the street.
Unchecked, the pair found themselves at the rear of the building which backs on to Downing Street.
The route allowed them to circumnavigate the gates installed by Margaret Thatcher to thwart terrorists amid the IRA bombing campaign in the 1980s.
They were then arrested under the Serious Organised Crime and Police Act.
Marius, 44, appeared in court on Thursday but his girlfriend, identified only as Miss Smith, was released without charge.
"I got into an area I should never have been allowed into," Marius told the Sunday Express.
"It really is a disgrace. I think they are going to drop the charges."
A Downing Street spokesman rejected suggestions that the pair had got inside No 10 and even Mr Blair's offices.
"The suggestion that there was an intrusion into the Prime Minister's office or the building of 10 Downing Street itself is totally wrong," he said.
