Nurse Killed In Edinburgh Police Chase Tragedy
A nurse has been knocked down and killed by a car being chased by police in Edinburgh.
The woman, named locally as 33-year-old Jill Pirrie, is believed to have been walking home from work at Edinburgh Royal Infirmary when she was struck by the car on Old Dalkeith Road at around 8pm on Thursday.
Ms Pirrie, who is understood to have a young son, was treated at the scene but later died in hospital.
Police Scotland said a force vehicle was following a silver Ford Ka after it failed to stop for officers.
The police car's blue lights and siren were being used in the pursuit, the force said.
No arrests have been made and officers are continuing to appeal for witnesses.
A Police Scotland spokesman said: "The silver Ford Ka that was involved in the collision was being followed by a police vehicle at the time, which had blue lights and siren activated, after it failed to stop when signalled to do so by officers.''
The Police Investigations and Review Commissioner (Pirc) is also reviewing the circumstances that led to the death.
A spokeswoman said: "A police vehicle was following a silver Ford Ka when the Ka was involved in a collision which resulted in the death of a 33-year-old woman in Edinburgh.
"The Crown Office and Procurator Fiscal Service (COPFS) has instructed the Pirc to carry out an independent investigation into the circumstances leading up to the incident.
"Pirc investigators attended the scene in the early hours of the morning and a report will be submitted to the COPFS in due course.''
