LAKE CITY, Fla. — A Lake City nurse was arrested on Tuesday after the Florida Department of Law Enforcement says he sexually assaulted a child patient then tried to solicit the victim for sex. 

An investigation into the incident began on Thursday. Investigators say Matthew Neil Melvin, 41, inappropriately touched the child during a physical exam and later sent sexual messages to the boy via Snapchat. 

An undercover agent posed as the child and began exchanging messages with Melvin. During the conversation, FDLE says Melvin indicated he wanted to sexually assault the child and sent a photo of his underwear showing his groin area.

Melvin also tried to meet with the child, investigators say.

Additional charges against Melvin are pending.

If you have any information on Melvin regarding the incident, call FDLE Live Oak at 1-800-226-5630.
