A Mid North Coast resident has launched NSW Supreme Court action against the NSW Police over their treatment of him in relation to the investigation of William Tyrrell's disappearance from Kendall in 2014.
A spokesperson for Bill Spedding's lawyer Peter O'Brien confirmed Mr Spedding recently started proceedings against NSW Police, for misfeasance in public office and malicious prosecution.
Mr Spedding was investigated by police not long after three-year-old William went missing from his foster grandmother's home at Benaroon Drive, Kendall on September 12, 2014.
In an interview on ABC's Four Corners program which will air on Monday, November 4, Mr Spedding is set to detail the impact the investigation has taken on his personal life and business.
Former Detective Chief Inspector on the case, Gary Jubelin is also expected to appear on the program.
Mr Spedding has always strongly denied any involvement in relation to William's disappearance.
At the time of the incident in 2014, Mr Spedding was living in Bonny Hills and ran his own business as a washing machine repairman.
He was hired by William's foster grandmother to fix a washing machine at the property, days before William disappeared.
