INDIANAPOLIS - A suspicious notebook has prompted a police investigation at a downtown Indianapolis high rise office building after officers said they found what could be "suspicious threats and drawings" of the building.
Police have notified the U.S. Department of Homeland Security as they begin searching for the person who left the notebook inside a weight room at the Capital Center twin office towers in the 200 block of North Illinois Street.
Officers said the concern was caused by a 4-inch by 7-inch brown notebook that was left inside a first-floor weight room that can be accessed by keycards carried by tenants of the office complex.
Police wrote in their report that the notebook contained various handwritten names, as well as references to rocket launchers, AK-47 assault rifles, a sniper rifle and other firearms.
The notebook also contained a Nazi emblem and a drawing of a plane with a bomb that appeared to be flying into the north tower of the Capital Center building, officers wrote in their investigation report.
The report specified that one drawing appeared to depict the two Capital Center buildings with an arrow pointing up to the midway point of the north tower.
Officers said the building manager was planning to check surveillance videos of the weight room where the notebook was left, while also checking which tenants may have accessed the room with their key card over the weekend when the notebook was located.
Police photographed each page of the notebook, while placing it in the police property room as evidence.
When the Call 6 Investigators arrived at the building manager's office Wednesday afternoon, a worker said that tenants hadn't been told about the threat. She said nothing further had been discovered about the ordeal since the notebook was found.
The building manager did not respond to a request for comment.
