William Tyrrell’s foster parents have been charged over the alleged assault of a child.
NSW Police from the taskforce investigating the three-year-old’s disappearance on Wednesday revealed a 56-year-old woman and 54-year-old man were each facing one charge of common assault.
They will face Hornsby Local Court over the matter on Tuesday, November 23.
The new charges come as a team of detectives scour the Kendall home on the NSW mid north coast where William was last seen before he disappeared in September 2014.
Two pieces of degraded material have been found by police at the William Tyrrell dig site – with officers comparing them to samples of a red and blue Spiderman suit.
Just after 2pm on Wednesday unformed officers and forensic experts gathered excitedly around a spot in the cleared earth area along Batar Creek Road, Kendall on NSW’s mid-north coast.
NSW Police Detective Mark Duke pulled a sample of Spiderman suit cloth from his pocket along with images of the missing three-year-old in the suit he was last seen in.
Mr Duke then compared with it with an object unearthed from the ground. The item caused police to don gloves, place the item in an evidence bag and take it to a parked forensic van.
However, after some initial excitement, a police spokeswoman swiftly intervened to rule the item was unrelated and not of relevance to the case.

This was after NSW Police Commissioner Mick Fuller called into the scene to see what was happening after seeing a live Sky News Australia report about the find.
Police had placed a sign saying forensic number eight on the ground next to whatever they had uncovered and then used a brush to clear further earth from the surface.
Four detectives and seven police grouped around the potential find as a female officer brought out a small blue tarpaulin to cover the area.
Police then painstakingly dug by hand around the root of a plant, cautiously removing evidence.
The item found appeared to be a disintegrated piece of threaded material.
After 30 minutes, police began patting forensic expert Professor Jon Olley on his shoulder.
About 3.15pm, police made a second possible find which Det. Duke compared with a Spiderman suit image on his phone.
He took photos on his phone of the item, which was also possibly fabric and placed an evidence marker beside it.

Uniformed police appeared to pour a liquid over the item before placing it in a brown paper bag.
That area and the location of the first find of a degraded piece of patterned fabric has now been pegged with blue plastic flag markers.
A cadaver dog was taken over the area and the whole scene covered with large rolls of black plastic.
Daily Mail Australia revealed earlier on Wednesday that police believe the site along Batar Creek Road is linked to the recent seizure of William’s foster grandmother’s car.
It is understood the car travelled near the site on the day of William’s disappearance with police investigating if an object was thrown out the window.
A car seized by police looking for the remains of William Tyrrell was allegedly driven by his foster mother on the morning he vanished seven years ago. Police believe an object might have been thrown from the vehicle as it was driven along Batar Road at Kendall, which is in the middle of the massive police search site for William’s body

Earlier on Wednesday, a ‘body finder’ who helped discover the remains of murdered schoolboy Daniel Morcombe claimed the dig to find William’s remains is a ‘more complex’ job.
Speaking exclusively with Daily Mail Australia before going to a high-powered meeting with detectives at the Tyrrell search command post, water science expert Professor Jon Olley toured one of the possible burial sites now cordoned off by police tape on Wednesday morning.
Daily Mail Australia exclusively photographed both the site inspection and the professor’s briefing with police.
Along with two detectives and special task force police officers, the grim-faced professor joined forensic grave archaeologist, Dr Tony Lowe, to inspect an area which has been flattened and cleared by Rural Fire Service officers.

The site, which has a mound of earth dug up by an excavator, is on a dirt road connected via a fire trail up through dense bush to the house where William vanished in 2014.
Professor Olley said the task of finding William’s remains was more difficult because it was over ‘a bigger area’.
In 2011, the Griffith University emeritus hydrology professor spent two months with a team of hydrologists and archaeologists searching on a steep swampy site near the Glasshouse Mountains on Queensland’s Sunshine Coast.
They found two shoes and three bones belonging to Daniel Morcombe, 13 years old at the time of his murder, whose body had been discarded by killer Brett Peter Cowan at the site in December 2003.
