An Indiana man was charged Wednesday on accusations he stalked WNBA player Sophie Cunningham and sent her threatening and explicit messages on social media.

Kevin Singh, 48, faces felony charges for stalking and intimidation, as well as a misdemeanor harassment charge. He was arrested Tuesday, according to the Marion County Prosecutor’s Office.

Cunningham, a player with the Indiana Fever, told investigators she had been staying at home more and having nightmares because of Singh’s continued messages, according to the affidavit. She was first made aware of Singh’s alleged online conduct in February, she said.

Singh’s online behavior escalated that month and his conduct “became increasingly threatening after he was contacted by team security,” the Marion County Prosecutor’s Office said in a news release.
