PORTLAND — A Windham man faces 68 felony charges for sex crimes after being indicted last week by a grand jury at Cumberland County Superior Court.

Nicholas Gladu, 27, faces one count of unlawful sexual contact and one count of sexual exploitation of a minor. Both of those counts are class A felonies, punishable by up to 30 years in prison.

Gladu also faces one class C felony charge for visual sexual aggression against a child under the age of 12, and 65 class C felony charges for possession of sexually explicit materials. Class C crimes are punishable by up to five years in prison.

Lt. Michael Nugent of the Westbrook Police Department issued a press release this afternoon. He said Westbrook, Windham, the Maine Computer Crimes Task Force and the Cumberland County District Attorney’s Office worked together on the four-month investigation of Gladu. The crimes allegedly happened between August and October of 2010.

Gladu is being held on $100,000 cash or $500,000 property bond at the Cumberland County Jail.

“The matter continues to be investigated and additional charges may be filed as more information becomes available,” Nugent wrote in the press release.
