THE FBI is investigating social-media threats made against New York Islanders defenseman

Nick Leddy.

FBI spokesman J. Peter Donald confirmed the investigation in an email yesterday to the Associated Press.

Islanders spokesman Kimber Auerbach said Leddy and his family are safe and the NHL has been alerted to the situation.

Newsday reported that a now-suspended Twitter account posted pictures of Leddy's Minnesota driver's license and a credit card. It also made violent threats against him.

The Twitter account had been posting harassing photos of Leddy, a teammate and others in recent months.

The 24-year-old signed a 7-year, $38.5 million contract extension Feb. 24.
