Tony Blair’s daughter, Kathryn, held at gunpoint in attempted robbery

Tony Blair's daughter was held at gunpoint during an attempted robbery in central London, according to police.

Kathryn Blair, 25, came face-to-face with the men at around 8:30 p.m. Monday while she and her boyfriend were walking their dog in London's posh Marylebone neighborhood.

The two men, one armed with a gun, demanded cash and jewelry before suddenly fleeing empty-handed.

While shocked, the former prime minister's daughter and her boyfriend were unharmed.

No arrests had yet been made, though police planned to increase patrols in the area.

Police said one of the suspects was wearing dark clothing and a balaclava, while the other had a scarf wrapped around his face.

Officers believe the incident is linked to another attempted robbery about 30 minutes earlier.

Kathryn Blair, who's an attorney like her parents, had just returned to London from her brother Euan’s weekend wedding to Suzanne Ashman.
