Parents at a school for disabled children were left stunned and angry when a police riot van pulled up at the school gates and started dishing out on-the-spot fines.
Many of the parents were helping their children in wheelchairs to their cars when the officers appeared.
One parent, Dave Philips whose wheelchair-bound son Matthew attends Hilltop Special School in Maltby near Rotherham, was handed a £30 fixed penalty when he pulled up.
Dave told the Daily Mail: 'The police response has been heavy handed – and it's the kids they're penalising, not us. The police behaviour was unpleasant and completely unnecessary.
'Nine officers and a police van created an intimidating atmosphere around the school. I was approached by a young policewoman who told me to "move" – not "excuse me sir"– it was just a total ignorant attitude.
"I explained to the officer I was going to park here for five minutes to get my son. I said: "He's a wheelchair user and we have got a side loading lift." "Not my problem," was the reply.
School head teacher Peter Leach said there had been long standing problems with parking as the school was in a quiet residential area and the numbers of pupils had grown significantly in recent years.
He said: 'I don't know why so many officers were sent. I was somewhat surprised that they made such a big issue of it. As a result we are asking parents to be careful where they park.'
A spokesman for South Yorkshire Police said: 'Badly parked vehicles in the area cause disruption and can be dangerous. They only turned up in a riot van because it was the only vehicle available at the time.
'Leaflets have been handed out as it has become a contentious issue with parents and we need to ensure the safety of children. We are asking parents to park considerately and this operation will continue.'
