When three robbers targeted the home of self-confessed 'geek' Jack Cunningham, they didn't expect to leave empty-handed.
But the would-be burglars got a short, sharp shock when unassuming Jack saw them off with his bare hands - thanks to 18 years of martial arts training.
Jack, 22, who cuts a modest figure in glasses, used his taekwondo skills to chase away masked robbers raiding his parents home.
But the part-time lifeguard was left with a black eye after his grapple with the group. His father, 48, was also injured.
Jack, from Baddeley Green, Staffordshire, said the burglars - who fled empty handed - came off worse and declared: "They picked on the wrong house that day."
"They asked for 'Marcus', but I told them no-one called Marcus lived here and they must have the wrong house.
"I was closing the door when one of them grabbed me from behind and pulled me to the floor.
"I must have looked like an easy target, I wear glasses and maybe they thought I was a bit of a geek but I soon proved them wrong.
"I've done taekwondo since I was four, so they really picked the wrong house and the wrong bloke to mess with.
"It all happened so quickly. I've done the training for so long that it just comes naturally and it helped me get an advantage.
"I had a bit of a scrap with them, then one of them pulled a weapon out, but luckily my dad ran in armed with a mop.
"Then after a bit of a fight they ran away.
"I think they came off worse, although because they had weapons it could have been a lot more serious. They didn't manage to take anything.
"We have no idea why they came to us. I've never had any trouble with anyone in my life."
Staffordshire Police were hunting the three men who are believed to have targeted the wrong house at 2pm on Tuesday.
They want to speak to two white men and a man of mixed race. It is believed one had a knife. An air weapon was left at the house by the raiders.
Detective Sergeant Tim Boulton said: "This was a really frightening experience for the occupants, who fortunately were not seriously injured.
"This incident happened in broad daylight and at a time when people were about."
Jack’s girlfriend, Jaye Ashcroft, 19, was working at the time of the burglary.
She said: "It is not nice to see what they have done to Jack, but it was a relief that he was okay."
Residents also spoke of their shock following the raid.
Kay Bailey, 46, from nearby Edge View Road, said: "I don't understand what this could have been about."
Neighbour Pam Shuker, 61, added "It's incredible to think something like this could happen in broad daylight."
Police have arrested a 26-year-old man from Stoke-on-Trent in connection with the burglary.
