A formerly Summit-based pediatric gastroenterologist, who was arrested earlier this year and charged with sexually assaulting one of his patients on numerous occasions, now has been criminally charged in connection with similar alleged incidents involving two additional patients, acting Union County Prosecutor Lyndsay V. Ruotolo announced Friday.
In total, Michael Tyshkov, 65, of Livingston is now charged with two counts of second-degree sexual assault, one count of third-degree endangering the welfare of a child, and three counts of fourth-degree criminal sexual contact.
An investigation by the Special Victims Unit of the Union County Prosecutor’s Office, in collaboration with the Summit Police Department, revealed that the first identified victim, a 20-year-old female, 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.
Charges filed in connection with the two additional victims involve alleged crimes occurring on dates about four months apart in 2017, Zyriek added. The victims were 16 and 19, respectively, at the time. Tyshkov is alleged to have sexually assaulted all of the victims under the guise of a routine gastroenterology exam.
Tyshkov, who has surrendered his medical licenses in New Jersey and New York – he had a secondary practice on Staten Island – was free on pretrial release, with conditions including house arrest and electronic monitoring, when the new charges were filed. A second detention hearing in Superior Court took place Thursday morning, pursuant to which Tyshkov was released under the same conditions previously ordered by the court.
It is strongly believed that there may be additional victims associated with this defendant. Tyshkov is also believed to have had a number of Russian-language speaking patients. 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, while third-degree crimes can result in 3 to 5 years.
These criminal charges are mere accusations. Every defendant is presumed innocent unless and until proven guilty in a court of law.
