One of Denver's 15 public works directors, Kelly Duffy, and one of her top assistants are on paid leave while the city investigates unspecified personnel allegations, 9Wants to Know has learned.

Duffy is currently the director of Denver Public Works' street maintenance division.

Ryan Luby, a spokesman for the Denver City Attorney's Office, confirmed the investigation will be handled by an outside employment organization, which is already under contract with the city.

Duffy's computer was confiscated, Luby told 9NEWS. Confiscating city-owned electronics is standard procedure in an investigation like this, he said.

Duffy's current annual salary is $147,766.38.

Manager of Street Maintenance Operations Doug Legg is also on paid leave. Legg reports to Duffy.

Luby would not provide specifics about the allegations in the personnel investigation into either employee.
