Radlett man Rikki Constable was jailed for six months today (Friday) after being caught for the second time with a knife.
Constable, 26, threw the locking knife away when he was approached by two officers at Bourne End services on the A41 near Hemel.
It hit the windscreen of a nearby car, causing £75 damage, St Albans crown court heard.
Prosecutor Matthew Pardoe said the car had triggered an automatic number plate marker and was seen at the services at ten to two in the afternoon of August 7 last year.
“He (Constable) was alone and was asked to step out. He grabbed an object from the back of the vehicle and threw it. It flew across the car park and landed on a windscreen, causing a crack.”
Constable, of Battlers Green Drive, appeared from Bedford prison via a video link and pleaded guilty to having a bladed article and causing criminal damage. In October 2017 he had a condition for possessing a knife, meaning that he faces an automatic six-month sentence.
Will Noble, defending, said Constable made full admissions in interview.
Judge Caroline Wigin said: “There was no suggestion the knife was used to threaten or intimidate.”
She told Constable: “You were in possession of this lock knife and were no doubt panicking.
“You threw it across the car park and it broke a windscreen.
“It was a foolish thing to do in the circumstances. It is fortunate it was only a window that suffered any damage.”
