A Summit-based pediatric gastroenterologist has been arrested and charged with sexually assaulting one of his patients on numerous occasions over the course of several years, acting Union County Prosecutor Michael A. Monahan announced Monday.

Michael Tyshkov, 62, of Livingston is charged with second-degree sexual assault and fourth-degree criminal sexual contact.

An investigation by the Prosecutor’s Office’s Special Victims Unit revealed that the 20-year-old female victim had been seen regularly for treatment by Tyshkov over the course of slightly more than a decade, according to Union County Assistant Prosecutor Stacey Zyriek, who is prosecuting the case.

The investigation revealed that the alleged sexual assaults occurred during medical exams taking place on numerous occasions from April 2016 through March 2019, Zyriek said.

Tyshkov was arrested without incident Friday and lodged in Union County Jail pending a first appearance and detention hearing.

Anyone with information about Tyshkov’s activities is being urged to contact Special Victims Unit Detective Jennifer Smith at 908-965-3814 or Summit Police Department Detective Christopher Medina at 908-273-0051.

Convictions on second-degree criminal charges are commonly punishable by 5 to 10 years in state prison.

These criminal charges are mere accusations. Each defendant is presumed innocent unless and until proven guilty in a court of law.
