Phil Tye, a member of the Silksworth service, said he planned to make a formal complaint about the handling of the case by the police.
He and his co-accused Andrew Laverick were scheduled to appear before South Tyneside magistrates on Tuesday, June 22.
Cllr Tye, of Castlereagh Street, Silksworth, and Mr Laverick, of Bedford Place, Silksworth, were facing a charge of allowing several persons 16 and under to use a motor vehicle at King George Playing Fields, at Palgrove Road, Pennywell, on Friday October 22 of last year.
But the charges were dropped and the charges against the couple were dismissed.
“I have been through hell for the past nine months,” said Cllr Tye.
“I am really, really, really unhappy with the Northumbria Police. At the moment I can’t say anything more as I will certainly press charges against a number of officers.
“I will absolutely pursue them through the formal complaints process.”
The charges relate to a multi-agency event at which Cllr Tye and Mr. Laverick were present as representatives of the community group Youth Almighty.
Cllr Tye said: “It’s something we’ve always done with young people – at no time has any young person driven this quad.
“This has not been disputed, despite the allegation. We have been asked to go.
“The kids would jump on the quad, have their photos taken and chat with us. No one ever doubted that this quad was turned off and not working.

Cllr Tye said the issue of insurance had not been raised at the time of the event
He said: “At no time did anyone ask for insurance. They did not request any documentation regarding this vehicle.
Several weeks after the event – in November of last year – he was contacted by police about the event.
He said: “I got a phone call in November asking me to come to Southwick and be interviewed. We were really, really confused as to why we were there.
“The concern was that a child photographed on the stationary quad could fall and have an accident.
“We had liability insurance and we had vehicle insurance and passenger insurance to use the quad on the road – that was not in dispute.”
The pair only found out at the last minute that the charges were dropped.
He is disappointed that he did not have his day in court and said: “The public should be given the opportunity to ask what this is about.”
A Northumbria Police spokesperson said: “Following a full and thorough investigation, an evidentiary package was prepared and a case was presented to the Crown Prosecution Service (CPS) against two individuals.
“However, we have since been informed by the CPS that due to evidentiary difficulties the case has been closed and we respect this ruling.”
