Estate agent Asif Ali, 35, confronted the men after they broke into his home in Bamford, Greater Manchester, at around 9.15pm on Tuesday night.
In CCTV footage of his brave defence of his home, Mr Ali is seen landing a flurry of blows on one thug before two accomplices join the brawl and he fights them off too.
Today Mr Ali explained how his first thought was to protect his wife Charlotte, 30, who was asleep in bed at the time of the attack.
The businessman immediately confronts him and ducks a left-handed punch from the thug.
He then launches a flurry of jabs of his own, pummelling him into a corner of his home.
He tries to shut the door but one thug keeps it open and storms back in the house as Mr Ali runs to his kitchen to pick up two kitchen knives.
However, Mr Ali forces the door back open and runs out to confront them again.
At the same time, his wife Charlotte, 30, who was upstairs in bed at the time of the invasion, emerges into the hallway.
While on the phone to the police, she runs outside to join her husband and the pair go back inside after the thugs have escaped.
A fourth member of the gang is then seen running through the garden of Mr Ali’s property with his phone pressed to his ear.
Today Mr Ali, who runs an estate agents and a clothes shop in Rochdale town centre, told how his first thought was to protect his wife Charlotte, 30, who was upstairs in bed when the raid took place.
The attempted robbery took place at Mr Ali’s home in Bamford at about 9.15pm yesterday.
‘He threw a punch at me and we started to fight.
‘I didn’t know what I was doing. Instinct just kicked in – I just trying to get him out of the house.
‘A second man came in and I thought he was trying to get upstairs where my wife was. I didn’t want them anywhere near my wife.
‘I got them outside, but they were pulling at the door, then one of them pulled out what looked like a knife, but the police think it might have been a screwdriver.
‘He said ‘I’m going to kill you’.
Mr Ali says he’s released the CCTV footage in a bid to catch those responsible and is offering a £5,000 reward for any information which leads to a conviction.
He added: ‘It’s still not sunk in, I don’t think.
‘It was surreal. That someone could be so brazen and just walk into someone’s house like that is unbelievable.
‘We work hard, seven days a week sometimes, for what we have and it makes me angry that some people think they can just come and take that.
‘They knew we were home. The lights were on, the cars were on the drive, the doors were open, and they’ve come into our home armed, knowing there were people inside, knowing there would likely be a confrontation and knowing they would cause some damage.
‘Someone out there knows who these people are. They need to be caught before they do it again.’
