A teenager called police to report a man was brandishing a knife in public - but it turned out to be him carrying the blade.
Jack Barrass, 19, has been sent to prison for nine months after being caught by police in possession of the knife on March 24.
The teenager had called police to claim that he had witnessed a man waving a knife above his head on St James' Crescent in Benwell.
When police arrived they spotted a man who matched the description of the person given by the caller.
Officers approached him and carried out a stop and search, at which point the man admitted he had a knife tucked into his trousers.
Bodycam footage of the search has been shared by the force, showing Barrass admitting he has a knife seconds after being approached by an officer.
A large blade is then carefully removed from his trousers by the officer with Barrass in handcuffs.
He then told police his name and admitted that it was HE who made the call to police.

Barrass was later charged with possession of a bladed article and was jailed for six months by magistrates the day after his arrest.
However, a court was told that Barrass was already subject to a nine month suspended prison sentence for the exact same offence just five months before.
As a result, he was committed to prison for nine months when he appeared before South East Magistrates’ Court last month.
Following the case, Neighbourhood Inspector Alan Davison criticised Barrass and said he could have diverted officers away from other victims who needed their help.
He said: "Carrying a knife in public is a serious offence regardless of the circumstances.
"If a person is in possession of a knife then there is always a chance that it could be used to do serious injury to another person.
"Even if the calls are just a prank, they require an immediate police response and that puts a strain on our resources.
"It means officers are having to attend the scene to place him under arrest when they could be helping other victims of crime.
"I am glad the courts have taken this incident so seriously and that Barrass will now spend the next few months behind bars.
"This sentence should act as a strong deterrent to anyone who thinks it is acceptable to carry a knife in public or make a hoax call to police."
Barrass, of St James' Crescent, Benwell , was also made to pay a £115 surcharge to fund victims' services.
