The son of an Ontario Provincial Police officer who's facing more than 100 charges alleging sexual assault, making and distributing child pornography and bestiality made a court appearance on Friday.

Shayne Lund, 22, mouthed the words 'are you OK' to his father who was in the front row of a Barrie, Ont., courtroom. His father, Mark Lund, nodded yes.

The case involves Lund and two other co-accused women who have been described as his girlfriends — 19-year-old Kathryn Thompson and 20-year-old Avery Taylor.

'There's a number of people who need to be spoken to, potential witnesses, victims as well, and we don't want to compromise the integrity of the investigation.'- OPP Sgt. Peter Leon

The CBC's Shannon Martin said the OPP have released virtually no information in the case and the Crown prosecutor Indy Kandola has cited "serious concerns about obstructive behaviour."

On Friday the Crown handed over a hard drive containing a significant amount of material to the defence lawyers.

Sgt. Peter Leon told CBC that the "investigation is ongoing."

"There's a number of people who need to be spoken to, potential witnesses, victims as well, and we don't want to compromise the integrity of the investigation," he said.

The victims identified so far are all young girls between the ages of two and 10 years old.

Angela McLeod, the lawyer for Thompson, said she has raised concerns over the OPP investigating the family of one of their own officers.

"Should the OPP officers who are investigating have been doing so ?" she said. "Should they continue on the case? Where was Mr. Lund Jr. living at the time?"
