Footage shows the shocking moment an 'armed man' lay dying in the street after being shot by police in Milton Keynes today.

The disturbing video shows the man - who a witness said looked to be in his mid 20s - bleeding from his stomach area after being shot.

Armed police had attended a call out just before 1pm outside Milton Keynes train station, in Elder Gate, on April 1.

A local man said he heard a gunshot and rushed out of a cafe to find two officers trying to revive the man - who was "gasping". "

The officers gave CPR, the local said, but the man is said to have died at the scene.

Two ambulances arrived and the roads were closed, he said.

A police statement said: "Officers from Thames Valley Police and British Transport Police were called to reports of a man carrying a fire arm at Milton Keynes railway station at 12.55."

"Armed officers responded and challenged the man, before shots were fired by police."

The local, Domenico Scalzo, 38, a delivery driver, said: "It was very shocking - I will definitely have nightmares."

"It's really difficult for the police, there are teenagers around here as young as 12 carrying massive knives, but you don't expect to see people gunned down in the streets by the police in the UK."

"I was having my coffee and I saw a police Volvo arrive."

"I heard a pop - I used to work with firearms in private security, I knew it wasn't a car backfiring or anything."

"When I went out people were crowding around and I could see the hole in his stomach and blood gushing out."

"They turned him to look for an exit wound and then laid him flat and started doing compressions."

"I heard him gasping - it's a very slow and painful way to die."

Domenico, an Italian national, said he's lived in the UK for 13 years - seven in London before moving to Milton Keynes.

He said: "I've lived in places that are more dangerous and never seen anything like this before."
