A pregnant Lincoln woman was shocked when police threatened her unborn child with an Asbo.
Charlotte Childs, 33, was invited to attend a meeting to discuss her naughty son, reports The Mirror.
The letter even addressed her baby by one of the names she and husband Damien, 29, are planning to give him.
Charlotte, who is 36 weeks' pregnant, said: "The letter said there had been an incident of anti-social behaviour and our child was identified.
"I would love to know how a 36-week-old foetus has managed to go to the park and cause trouble without me noticing.
"I find the whole thing hilarious, especially as I'm this close to having my first child."
Damien, 29, added: "There was a request to attend the equivalent of a parenting class with regards to the anti-social behaviour of my unborn son.
"Just two weeks prior to that there had been some anti-social behaviour on the street and we were really pleased with the police response time."
The letter was sent to the couple's home and was addressed for the attention of the boy's guardians.
Embarrassed police and council officials have since apologised. One of the alleged troublemakers has the same surname.
