PINELLAS COUNTY, Fla. -- Former state Sen. Jack Latvala will not face charges after a law enforcement investigation into sexual misconduct allegations.

The announcement was made by State Attorney Jack Campbell.

Latvala, a longtime Republican lawmaker from Pinellas County, was accused of making inappropriate comments and unwanted physical contact against a female Florida Senate staff member over a period of four years.

A Florida Senate investigation also determined that he may have broken the law by offering a witness his support in exchange for sex acts.

Latvala resigned from his post in December.

Campbell said there wasn't enough evidence to prosecute Latvala.

"On behalf of the Senate, I thank the Florida Department of Law Enforcement and State Attorney Jack Campbell for their fair, thorough, and independent investigation," Florida Senate President Joe Negron said in a prepared statement.

Latvala has denied any wrongdoing and on Friday praised "good law enforcement people who weren't influenced" by politics.
