Fire that gutted Sydney council chambers set by angry driver over '$200 parking ticket'

Police believe they have a new lead on who caused a serious fire that led to an estimated $27 million in damage to the Liverpool Council chambers seven years ago.

For seven years the blaze has stumped detectives.

It was initially thought disgruntled members of the public were to blame after council granted approval for an Islamic school in Hoxton Park.

More than 80 firefighters fought the inferno in 2010 but it was unstoppable and within minutes the building was charred rubble.

But now police believe they know who did it.

Detective Superintendent Murray Chapman said police believe the fire may have been deliberately lit by a person angry about a council-issued parking fine.

"Detectives are sifting through thousands of council issued infringement's dating back to 2010,” he said.

“A painstaking process but investigators believe they will be able to narrow in on those responsible.”

It’s believed $27 million worth of damage was over a $200 parking ticket.

Police also suspect others might be helping cover up the crime and warn it could land them behind bars too.
