MILWAUKEE (AP) _ A man who called himself ``Dr. Chaos'' and was accused of storing cyanide in the Chicago subways was charged Tuesday with committing 53 acts of vandalism in Wisconsin.

Joseph Konopka, 25, was accused in an indictment Tuesday of targeting power installations, telecommunications equipment and air navigation systems in 13 counties.

U.S. Attorney Steven M. Biskupic said Konopka caused more than $800,000 in damage and about 28 power outages and other service interruptions affecting more than 30,000 power customers.

Konopka, who went by the online name ``Dr. Chaos'', was charged March 11 in Chicago with possession of a chemical weapon.

The FBI said he claimed to be the leader of a Wisconsin group of vandals known as the Realm of Chaos.
