(CNN) -- The Florida Department of Law Enforcement will close a criminal investigation into former U.S. Rep. Mark Foley on Friday without filing charges, two law enforcement sources said Thursday.

Authorities were investigating whether Foley might have used computers in Florida to engage or solicit minors in any illegal activities.

The Republican, who represented Florida's 16th District in Congress, resigned in September 2006 after suggestive e-mails and instant messages he had written to teenage House pages surfaced in the media.

Florida agency spokeswoman Heather Smith said last month that investigators hoped to finish their work within two weeks and that results of the investigation would be turned over to State Attorney Bill Eddins in Pensacola, Florida, where Foley was at the time he is said to have communicated with a young man.

But the agency said the House of Representatives had blocked efforts to review files on computers Foley used in his congressional office. Smith said the agency was working with the FBI and Foley's lawyers to review the contents of those computers, which are federally owned.

Foley's attorneys had denied that he ever engaged in sexual activity with minors.

"I have no comment," Foley's attorney David Roth said Thursday when asked about the reported closure of the Florida investigation. "I cannot confirm or deny your report."

A federal investigation of Foley has been closed for some time, according to sources.

Foley entered a treatment facility for alcoholism shortly after he resigned and revealed that he is gay and was molested by a priest when he was between the ages of 13 and 15.

A House Ethics Committee investigation of the scandal concluded in December 2006 that House GOP leaders were negligent in not protecting male teenage pages from possible improper advances by Foley. But the panel said there were no violations of the House Code of Official Conduct and decided that no one would be reprimanded.

A Justice Department report issued a month later said the FBI should have notified the House or other officials when members first learned of inappropriate e-mails. The FBI acted within its "range of discretion" when it initially decided not to open a criminal investigation in the case, the Justice Department said. But the internal watchdog's investigation concluded that simply filing away the complaint from a public interest group was an inadequate response.
