A man who confronted the Munich killer from the balcony of his flat has told Mail Online he would have shot the killer if he had a gun.

Thomas Salbey, who has become known as the 'balcony man' after his profanity-laced exchange with killer Ali Sonboly went viral, said he wished he could have fired back at the killer.

'All I had was a beer bottle to throw at him. If I had a gun I would have shot him I'd have shot him in the head,' Mr Salbey told Mail Online.

'What I said to him at the time still holds true. He is a coward who killed innocent people because he was not right in the head. He disgusts me,' he said.

Mr Salbey was on the balcony of his fifth floor flat overlooking the parking garage at the Olympic shopping centre on Friday.

He had heard the initial burst of gunfire after 18-year-old Sonboly shot teens at a McDonald's restaurant having lured them there using a fake Facebook page with the promise of free food.

Sonboly continued his rampage through the shopping centre before emerging on the concrete upper floor of the garage.

Nine people were killed and ten others injured by German-Iranian Sonboly, who later took his own life.

The block of flats where Mr Salbey lives alone. He had been drinking beer after work when the shooting broke out

Police in the city of Munich said the teen had no links to any terror group and described him as a deranged loner who was obsessed with shooting sprees.

Mr Salbey, who is single and lives in a dingy one-bedroom flat, was standing on his balcony when he heard the first shots fired on Friday evening.

He said: 'I was drinking a beer after work when I heard the shots, first at McDonald's. Bam bam bam – that's how it sounded.

'This was just below our house. At first I thought it was a Kalashnikov he was firing. Then I looked down from the balcony and saw him running along the glass tunnel.

'As he reloaded his gun I got my beer bottle and threw it at him. It broke on the glass, but I don't think he heard it.'

But the bottle attracted the attention of Sonboly, who made his way on the to car park roof after leaving a trail of bodies in the shopping centre.

Mr Salbey began shouting at the killer, who was dressed all in black - prompting the killer to fire several shots in his direction.

He said: 'At the time I was not sure if they were real of they were blanks. I now know they were for real.

'I hit the floor immediately, but I did see that he appeared to have gone quiet on the parking deck. By this time the police had arrived in front of the shopping centre.

'They didn't know where he was, so I called over to them - "He's there, up on the car park roof". I wasn't afraid.'

While Mr Salbey and Sonboly shouted at each other a 20-year-old neighbour, known only as Mersad, filmed the exchange on his mobile phone.

It was quickly uploaded to the Internet which led to Mr Salbey becoming something of a media sensation.

Ali Sonboly (left) had apparently hacked into a Facebook page to lure teens to the McDonald's where he shot dead nine people, including Can Leyla, 15, (right)

He invited Mail Online into his untidy flat.

In his bedroom a five-foot long radio controlled plane and a poster of a naked blonde hang over his bed.

Other pin-up pictures of topless women adorned the walls, while almost every piece of space in the flat was taken up with his belongings.

Mr Salbey said he had nothing but sympathy for those who lost loved ones.

'This should not have happened. I don't know how he got a gun.' he said.

Mersad's phone has now been seized by police and the video will form part of the investigation.

Teams of investigators in Munich are trying to determine how Sonboly was able to get the 9mm Glock handgun used in the rampage.

Germany has some of the strictest guns laws in the world and as Sonboly had psychiatric issues he would not have been able to get a licence for a firearm.

Police said the serial number on the pistol had been filed away but forensic teams will be studying the rifling in the barrel to see if the gun has been used in any previous shooting
