A Darien man charged with sexually abusing a high school student in 2009 pleaded not guilty during his Monday afternoon arraignment at the Will County courthouse.

Timothy Hagan, 39, appeared before Judge Richard Schoenstedt with two attorneys, Dave Carlson of Joliet and Terry Ekl of Lisle.

Hagan was working as the network administrator for the Lockport Township High School District when he sexually abused a 17-year-old in 2009, according to a statement released in May by the Lockport Police Department.

The statement said Hagan was "in a position of authority" over the teenage student.

The details of the authority Hagan supposedly wielded over the teenage girl were not mentioned during his brief arraignment. His attorneys cited the early stages of the case in declining to comment on the allegations.

Hagan's illicit relationship with the teen came to light after she "made an outcry to a family friend," according to the same Lockport police statement.

Schoenstedt assigned the case to Judge Carla Alessio Policandriotes and scheduled a July 19 pretrial hearing.

Hagan is free on a $10,000 bond. He made no statement in court but for his plea of not guilty.
