Police believe the incident involving Ms Blair and her friends is linked to another attempted robbery which happened in Boston Place about 30 minutes earlier.
The first incident involved a female victim and a male suspect.
"On both occasions a firearm was seen but not used - no shots were fired.
"None of the victims were injured and nothing was stolen during the incidents," the spokesman added.
As well as daughter Kathryn, Tony and Cherie Blair have three sons, Euan, Nicholas and Leo. Kathryn, a barrister like her parents, is their third child.-BBC
