A grandad in the UK accidentally collected the wrong child from a school and brought her to a doctor’s appointment, it has been reported.

The unusual incident happened at Gillingham’s Napier primary school in Kent. The grandad picked the child up from the school and brought her to a scheduled doctor’s appointment.

The six-year-old girl shares the same name as the man's granddaughter and is in the same year as her.

The young girl accompanied him on a bus from the school to the doctor and was prescribed liquid paracetamol medicine before she was dropped back to her class. He was completely unaware that the girl was not his grandchild.

"I went ballistic” said the six-year-old’s father.

“I was boiling inside. The first thing I thought was the worst. I had to ask my daughter the sort of questions no parent ever wants to ask: 'Did he do this, did he do that?'."

He continued, "When your daughter has been walked round town and taken on a bus by a strange man, it makes you sick to the stomach. It's every parent's worst nightmare. Everyone knows to tell their children not to go with strangers, but I want to tell every parent in that school – tell them again tonight.”

"Thank God it was an innocent thing done by a confused old gentleman."

An investigation has been launched to the incident said the headteacher.

"I have also spoken with the mother of this child to offer our sincere apologies over this regrettable incident and to assure her that we are reviewing all our safeguarding policies – with the help of the council – to ensure this never happens again" she said.
