A teenage factory worker caught with a knife when he was stopped by police has been jailed for four months.
Adrian Krzyczkowski was already under the threat of a suspended jail sentence when he was spoken to by officers in the car park of the Aldi store in Spalding.
At Lincoln Crown Court on Tuesday, prosecutor Siward James-Moore said Krzyczkowski’s car was searched and the knife was found in the driver’s side pocket.
Krzyczkowski said he normally used the knife at work but was on holiday the day he was stopped.
The 19-year-old, of Edinburgh Drive, Spalding, admitted possession of a bladed article in a public place on April 11.
He also admitted breach of an eight month custody sentence suspended for 18 months which was imposed in March 2010 for house burglary.
Mr James-Moore said Krzyczkowski had breached the order both by committing a further offence and by his behaviour towards probation service staff during unpaid work sessions.
He told the court that Krzyczkowski was abusive to probation officers and on one occasion took alcohol into a session in contravention of the rules.
“It was unruly and unacceptable behaviour,” said Mr James-Moore.
Andrew Cogan, defending, said Krzyczkowski, who is currently working in a factory, agreed his behaviour had been unacceptable.
Judge Sean Morris ordered him to serve three months of the suspended sentence and a consecutive one-month term of custody for the knife offence.
He told Krzyczkowski: “This court gave you a chance by imposing a suspended sentence but in the last few months your behaviour has become intolerable.”
