STRATFORD — A dentist with a practice in Trumbull has been charged with multiple child sexual exploitation offenses after being arrested at the Stratford train station Friday, officials said.

Scott David Cohen, 39, of Stratford, was charged with enticement of a minor to engage in illegal sexual activity, travel with intent to engage in illicit sexual conduct, transfer of obscene material to minors, and sexual exploitation of children, according to a news release from the U.S. Attorney for Connecticut John Durham.

A criminal complaint against Cohen alleges that he used the username “drpinstripe13” to start talking to someone on Instagram who he believed was a 15-year-old girl. Durham said Cohen “expressed in graphic detail his desire to engage in sexual activity” in several chat conversation on the social media site.

“Cohen described a variety of sexual activities he wanted to have with the minor and sent her sexually explicit images of himself,” the news release said.

The complaint alleges that the minor told Cohen she lived out of state and planned to travel to New York to visit a relative. Cohen, who has a dentist practice in Trumbull, told the girl he was willing to reschedule patients at his practice to be able to meet up with her, the complaint said.

Cohen was arrested Friday afternoon after he went to the Stratford train station to meet the girl. Although officials did not explicitly say, it appears the girl might’ve been undercover law enforcement because the girl was labeled as such in quotation marks throughout the release.

After Cohen was arrested, he appeared in Bridgeport court and was ordered detained pending a detention hearing that has not yet been scheduled.
