New video shows Jane Richard being rescued by off-duty firefighter Matt Patterson

An amateur video has revealed how off-duty firefighter Matt Patterson came to the rescue of 7-year-old Jane Richard in the Boston Marathon terror attack which killed her 8-year-old brother Martin.

Matt Patterson wearing a red T-shirt is seen rushing to the aid of little Jane Richard, who lost a leg in the attack and remains hospitalized in a critical condition.

Jane Richard is seen sitting up and then lying in the middle of the road, moments after standing on the sidelines where she was photographed alongside her brother Martin.

The photograph reveals how Jane and Martin Richard were standing just yards from terror suspect Dzhokhar Tsarnaev.

Following the bomb attack others are filmed standing around stunned but Matt Patterson leaps into action.

Just before the explosion the firefighter had been enjoying a meal with his girlfriend in a nearby restaurant.

“This child for some reason just jumped at me – it was tunnel vision,” Matt Patterson said.

“I could see the damage. I could see that she needed a tourniquet. She needed surgery, it was obvious from what I saw.”

“I go up to a business guy and ask for his belt, he hands it over without hesitation. I have to stop the bleeding. I am making the tourniquet and another man comes and I ask him to hold it for pressure. I’m looking up and down the street – looking for where I can bring the child to an ambulance or more care.”

Matt Patterson and the other man ran with Jane Richard to a waiting ambulance. The girl has lost a leg and remains in a critical condition in hospital but is expected to survive her injuries.

Yesterday it emerged Jane Richard is an enthusiastic Irish dancer having attended classes at the Clifden Academy of Irish Dance in Milton since the age of three.

Several Irish dance groups are now raising money to support her.
