MOUNT OLIVE, NJ – A township man secretly filmed women while they were having sex, according to authorities.

The man, Phillip Johnson, 28, was first arrested Sept. 8 on allegations he “filmed multiple women engaged in sexual encounters without their knowledge, according to Morris County Prosecutor Frederic Knapp.

On Oct. 13, Johnson was hit with additional charges stemming from claims made by an 18-year-old woman who “reported that she had engaged in an act of sexual contact” with Johnson when she was 17, said Knapp. He said the girl did not know she was being filmed.

Johnson faces charges of endangering the welfare of children, permitting a child to engage in child pornography, manufacturing child pornography, invasion of privacy and witness tampering, said Knapp.

Johnson’s actions are still being scrutinized by police, said the prosecutor. “The investigation into the allegations of invasion of privacy is ongoing, and law enforcement is actively seeking to identify those woman that were filmed during these sexual encounters,” said Knapp. “Anyone with information relating to this ongoing investigation is urged to contact the Morris County Prosecutor’s Office Sex Crimes/Child Endangerment Unit at 973-285-6200 or the Detective Bureau of the Mt. Olive Police Department at 973-691-0850.”

Knapp said Johnson appeared before Mount Olive Municipal Court Judge Brian Levine, who set bail at $25,000 with a 10 percent cash option. The judge ruled that Johnson is to have no contact with the victim and no contact with any children.

The prosecutor thanked the Mount Olive Police Department, specifically Detective Eric Krouse and Sgt. Luis Sanchez. He also thanked the Morris County Prosecutor’s Office Sex Crimes/Child Endangerment Unit.
