Rescuer shouted ‘come on son’ at dying Pc after Westminster attack

A rescuer shouted “come on son” to murdered Pc Keith Palmer, amid desperate attempts to save him outside the Palace of Westminster, his inquest has heard.

Officers ran to help Pc Palmer, 48, after his killer Khalid Masood was shot dead.

Masood had crashed his hired car and run into New Palace Yard where he stabbed the officer who had stumbled by a low wall.

A “chilling” image showed Masood bearing down on the constable with a large knife in each hand.

He stood over Pc Palmer, stabbing him by the wall before being distracted by another officer.

Seconds later, Masood was shot dead by a plainclothes officer.

Frantic scenes of people rushing to offer first aid were captured on a mobile phone.

In audio played at the Old Bailey, there were shouts of: “Police officer stabbed in the head. Police officer stabbed in the head.”

He was described as having a “weak pulse” and losing blood while another person said: “He’s been stabbed in the back.”

A man could be heard urging Pc Palmer to fight for his life, shouting: “Keith, come on son.”

An ambulance arrived on the scene just before 3pm but efforts to save Pc Palmer’s life stopped at 3.15pm.

The “ferocious” attack on Pc Palmer came after Masood, 52, had mowed down and killed four pedestrians on Westminster Bridge on March 22 last year.
