Authorities are investigating three suspicious items found around downtown Madison on Wednesday.

Police said that two suspicious items removed from Madison's sewer system aren't related to an investigation into a string of pipe bombs found in a parking ramp in recent weeks.

At a late afternoon press conference, police spokesman Mike Hanson said that two of the items were uncovered by a bomb squad in the sewer system about a block from the state Capitol. The objects were removed at the intersection of Webster and Main streets.

These two objects were described as resembling piping, WISC-TV reported.
