(CBS News) A fate of a janitor who let six students inside their school after hours to pull a prank with Post-It Notes is still in limbo, CBS News Indianapolis affiliate WISH-TV reports.

The high school seniors put 11,000 notes all over Cascade High School.

The six were suspended.

Wednesday, dozens of other students were suspended for protesting the earlier suspension.

Thursday, all the students returned to school to serve an in-school suspension.

Superintendent Patrick Spray recommended that Kim Rouse, a custodian in the school at the time, be fired. A school board must vote whether to accept Spray's decision.
