London: In a bizarre incident, a five-year-old boy in the UK has been billed about £16 (Dh89) and threatened with legal action by his friend’s mother for failing to attend her son’s birthday party.

Alex Nash, from Cornwall, was invited to the party just before Christmas.

An invoice for £15.95 was sent by his school friend’s mother Julie Lawrence, who said Alex’s non-attendance left her out of pocket and his parents had her details to tell her he was not going.

Alex’s father Derek said he had been told he would be taken to the small claims court for refusing to pay.

Alex’s parents, from Torpoint, had accepted an invitation to the party at a dry ski slope in Plymouth, Devon, just before Christmas.

However, they realised their son was double-booked and due to spend time with his grandparents, which he did.

His parents said they had no contact information for Lawrence at that time.

They found the invoice in a brown envelope in his school bag last week.

“It was a proper invoice with full official details and even her bank details on it. I can understand that she’s upset about losing money. The money isn’t the issue, it’s the way she went about trying to get the money from me,” Nash was quoted as saying by BBC.

“She didn’t treat me like a human being, she treated me like a child and that I should do what she says,” he said.

In a short statement, Lawrence said: “All details were on the party invite. They had every detail needed to contact me.”

Nash said he had been told he was being taken to the small claims court because he was refusing to pay.
