The Federal Bureau of Investigation is conducting its second criminal investigation in Oshkosh in less than a month.

The new investigation was focused Thursday in the area of Congress and High avenues.

Agents in unmarked vehicles could be seen Thursday morning in the area of the 1300 Block of Summit Avenue in front of an apartment building and in a garage in the vicinity of the building.

An FBI spokesman would not discuss the nature of the investigation.

"We can confirm there is FBI operational activity in Oshkosh this morning," FBI spokesman Leonard Peace said. "There is no danger to the public associated with our operation."

Oshkosh Police Department spokesman Joe Nichols said local police are not involved in the investigation. He said Thurday's FBI activity is not related to a joint investigation with the FBI last month of a University of Wisconsin-Oshkosh student who is accused of making ricin, a deadly toxin, at a residence in the 800 block of Frederick Street.

Law enforcement agencies executed a warrant to search the Frederick Street building on Oct. 31. Kyle Allen Smith, a senior biology major from Sun Prairie, was subsequently arrested and charged with possession of ricin in federal court. If convicted, he faces a maximum of 10 years in prison, a $250,000 fine or both.
