A student has told how he chased a robber from his home after he was tied up and threatened with a knife at his dad's £5 million home.Police have confirmed they are investigating after the intruder burst in on 19-year-old George Zelonka while he was revising in his bedroom.
George said the man dressed all in black, wearing gloves and masked, forced him to lie face-down on his bedroom floor, while he tied him up with cable ties and brandished the blade in his face.
But, after breaking through his cable ties, he began shouting "you don't know who you are dealing with, get the f*** out."
He said at first the burglar was "jabbing his knife" at him, but "in the end he actually asked me 'can I go now?'"
George said he then chased the man barefoot for 100 yards, armed with an umbrella.
The teenager said: "Obviously it was terrifying. I only had a minute to think about it while he was tying me up.
"The first thing that came to my mind was that he was a burglar and he was going to steal things, but when I started hearing plastic bags I was worried he'd kill me.
"He told me he'd kill me if I moved while he was tying me up."
At this point, George leapt into action and jumped to his feet, somehow managing to snap the cable ties in the process.
He began shouting at the intruder saying, "You don't know who you are dealing with, get the f*** out.'
George continued: "If you're asking me how it felt after I freed myself from the ties, it was even more terrifying.
"I didn't know how it was going to go because obviously he had the knife."
The intruder, still brandishing the knife, began jabbing it towards George, in a defensive way.
George said: "He was backing out jabbing his knife at me to keep me away. In the end he actually asked me 'can I go now?'
"I grabbed the umbrella and followed him out. It's quite heavy and I thought I could do some damage with it so I kept chasing him."
George then chased the culprit barefoot 100 yards until he reached Hampstead Heath.
He added: I'm not sure it was totally me chasing him. He was running away. It was the adrenaline. I knew if I didn't chase him I would lose him so I just kept running."
He then called his dad and told him what had happened.
George's dad Paul Goldstein, a property developer, was at work at the time.
Mr Goldstein said: "At first I thought it was a prank, but he has never played a prank on me before though.
"He was very hysterical and I asked him whether I should call the police and he said yes. That's when I knew it wasn't a prank."
George is currently preparing to sit his A-Levels in theatre studies, film studies and psychology, with a view to study film at Exeter.
His dad said: "If you've got children it's something which you can understand that I am upset about.
"And I'm upset that someone has broken into my house, of course."
He also said he didn't know what the motive was, as the intruder ran past Paul's office with his laptop and wallet in full show.
Paul described George as a "nice, affable lad" who had "never been in a fight before" but was physically strong.
He said: "He hasn't got an aggressive bone in his body."
He added that George, who is half-American and British used to get teased as a youngster due to his "goofy accent."
He said: "I'm proud of him because it could be the making of him in terms of his self-confidence."
George added: "I'm relieved that he didn't hurt me, I just really want them to catch the guy. I don't want it to happen to anyone else."
