A father stormed into a house after he thought a man in his underpants had been giving his daughter ice lollies, a court heard.
A neighbour of a house in Little Hulton called the police after a report of a 'suspicious male' who had seen acting 'inappropriately' towards girls in the street.
The report stated that a male was handing out ice lollies to girls while dressed just in his underwear.
John Key, 48, became aware of the incident, and believed the man responsible was in the property which he entered.
In fact his daughter, aged six, was in another area playing with friends.
She returned home safely following the incident, Manchester Crown Court heard.
Key barged past the man's wife, who was trying to prevent him from entering the property, before he started looking around the house, believing his daughter may be there.
He was saying 'where's my daughter', prosecutor Claire Brocklebank said.
He also picked up the man's car keys, before using them to check whether she was in his car.
The court heard there was some 'argy-bargy' and a 'scuffle' inside the property between the two men.
Key left shortly after. His daughter wasn't aware of the incident.
Police attended later that day, on July 24. Key was arrested and identified.
It is unclear who the man in his underwear was.
Key, of Little Hulton, appeared in court and later pleaded guilty to affray.
The court heard that he has 24 previous convictions, including for offences of theft and burglary, but he has remained 'out of trouble' for 20 years.
Defending, Rob Kearney said: "It was a case of putting two and two together and coming up with five, but there were real concerns."
Judge Martin Rudland accepted it was a 'spur of the moment' incident involving an 'emotional reaction', but said Key should have rang the police.
The judge said: "This was an unfortunate event. You have shown that for 20 years you can keep out of trouble.
"There seems to be no doubt that there was indeed a man in his underpants giving lollipops to children, which is bound to excite some concern."
Judge Rudland sentenced Key to 28 days in prison.
But because he has observed a curfew for about 10 weeks, this meant he had served the sentence, as electronically monitored curfews can count towards a prison sentence.
