Four suspicious devices were discovered this morning on the campus of Sacramento State.

"They are tape-wrapped bundles, approximately baseball sized," Campus Police Chief Mark Iwasa said. 

Iwasa says officials closed part of State University Drive and evacuated an outpost building until Sacramento Police determined there was no danger.

It's not the first time officials have had to deal with this issue. 

"Really, since September of last year, we've been finding some tape-wrapped bundles in and around the campus," he said. 

While they've looked suspicious, so far none have been dangerous.
