The daughter of former British prime minister Tony Blair was held up at gunpoint in an attempted armed robbery in London but a spokesman for the family said Thursday she escaped unhurt.

Kathryn Blair, 25, a lawyer, was threatened by two men as she walked down a street in the upscale central London district of Marylebone with her boyfriend and a group of friends on Monday night.

"Kathryn was with a group of friends. No one was hurt and nothing was stolen," a spokesman for the Blair family said.

The Daily Telegraph reported that Kathryn Blair lives in a townhouse in the area and was walking her dog at the time.

London's Metropolitan Police confirmed that an incident had taken place in the area at 8:30 pm on Monday night but said that no arrests had been made yet.

"The victims were a man and a woman; the suspects were two males," a spokesman for the force said.

Police believe the incident was linked to another attempted robbery nearby 30 minutes earlier, and said Kathryn Blair did not appear to have been targeted because of who she was.

"On both occasions a firearm was seen but not used -- no shots were fired," the police spokesman added.

"None of the victims were injured and nothing was stolen during the incidents."

Blair was prime minister from 1997 to 2007, winning three straight elections for the center-left Labour party.

He faced huge opposition over his decision to involve Britain in the 2003 invasion of Iraq.

He is now an international Middle East peace envoy and highly-paid public speaker.
