MILWAUKEE -- Oak Creek police arrested a Milwaukee Fire Department lieutenant on Wednesday morning, Nov. 20. Police records showed he was arrested in uniform while he was on duty at an MFD facility.

A news release Monday, Nov. 25 from the Milwaukee Fire Department said officials were taking this matter very seriously and opened an internal investigation. To ensure compliance with the Oak Creek Police Department investigation, the Milwaukee Fire Department was unable to comment further, the news release said.

Oak Creek police confirmed the lieutenant's name is Robert Olson. Olson, 44, of Oak Creek, faces one count of sexual assault of a child under the age of 16.

Prosecutors said Olson sexually assaulted a 14-year-old girl multiple times.

Later, prosecutors said Olson sent messages to the girl, reading: "I am so sorry got what happened, I didn't mean to, please don't go, please don't tell anyone, I am going to prison, I'm going to get raped. I am so sorry...I want to help you..."

He also sent messages to the girl's family, prosecutors said, indicating that "in the last three months since this happened, I have done a ton of work to regain trust. I have already made extreme life changes and carry this every day like a 100-pound weight no matter what it looks like on the outside. I assure you I've taken ownership and I'm still trying to..."

Olson was in court for his initial appearance on Monday, Nov. 25. Cash bond was set at $7,500, and a preliminary hearing was scheduled for Dec. 2. He was ordered to have no contact with children under the age of 17.
