Instead of telling his wife-to-be about the problem, the 36-year-old instead decided to get out of the predicament on his own. He called the register office at St. George's Hall in Liverpool, disguised his voice and told them there was a bomb in the building, set to explode in the next 45 minutes.
Once guests arrived at the church, they were met by police and firefighters who were on full 'emergency mode' since it was only 11 days after the Boston Marathon bombing.
But the hoax did not work as none of the ceremonies that day were cancelled and McArdle was forced to come clean to his soon-to-be sister-in-law, who suspected that he had made the bomb threat.
To remedy the situation, McArdle tried to call off the hoax by phoning the venue with his own mobile – a call that was traced by police.
Last week, McArdle appeared in Liverpool Crown Court to plead guilty to one charge of making a threatening phone call. He was sentenced to 12 months imprisonment. According to reports, McArdle's fiancee has stood by him.
“If it was not so serious, the facts of this case have all the makings of a comedy,” McArdle's lawyer told the judge, “He just could not get the words to [his fiancee] to tell her what he had not done in relation to the [booking] forms.”
