Walter Maslanczuk remained held Thursday in the Bergen County Jail pending a first appearance in Central Judicial Processing Court in Hackensack following his arrest the day before.
Bergen County Prosecutor Mark Musella said borough police notified Special Victims Unit detectives in his office that Maslanczuk “engaged in sexual activity with a juvenile on numerous occasions over the past three years in Rutherford.”
The prosecutor didn't elaborate.
The investigators arrested Maslanczuk on charges of aggravated sexual contact, sexual assault and child endangerment following an investigation, Musella said.
The prosecutor thanked Rutherford police for their assistance.
