A drunken lout threatened to bomb a Bridlington supermarket's beer aisle, shouting "Allahu Akbar" over the phone to counter-terrorism police.
"Stupid" Daniel Butler, of Trentham Close, could face prison, after making four hoax phone calls to the anti-terrorism hotline.
Appearing at Beverley Magistrates' Court today (February 4), the 21-year-old wore a blue and grey jumper and held his head in his hands, after pleading guilty to making the hoax calls.
He also admitted to a separate offence on November 3 2015 when he damaged a police officer's GPS tag
Prosecuting, Sally Robinson, said Butler had been drinking cider with his friends before making the hoax calls.
She said: "At 21.15 he calls the anti-terrorist hotline and said there was a bomb in Tesco in Bridlington.
"The officer asks how he knows this and he said he could see it and there's a man saying he will bomb us all.
"She then hears laughing and they put the phone down."
The court heard Butler made a second phone call to the hotline at 9.30pm, telling the officer she was "racist" and that he was going to bomb Tesco and was shouting "Allahu Akbar".
Two Tesco workers later described to police how they saw three men in the supermarket's foyer, and overheard one saying: "I'm going to put the bomb in the beer aisle at Tesco so it burns quicker".
Officers later arrested Butler after finding him walking in the direction of the house he lives at with his grandparents.
During police interview he told officers his level of alcohol intoxication was "eight out of ten".
In mitigation, Michael Robinson said Butler had pleaded guilty at the first available opportunity, and had secured a job interview at Costa Coffee in Bridlington.
He said: "Unfortunately he was drinking at the time. I am sorry to say he was intoxicated at the time and accepts being so in an interview by the police.
"He was with a friend and was showing off. It is right to say there are no aggravating features.
"This was a very stupid act by Mr Butler."
But chairman of the bench Mr A Hardman instead remanded Butler in custody, due to his, at times, poor record of cooperating with the probation service.
Butler will appear at Hull Crown Court on Friday February 26.
