INDIANAPOLIS (AP): Police say they’ve found about 25 marijuana plants found at an Indianapolis elementary school.

The Indianapolis Star and TV station WRTV report the plants were found growing Monday night in a small cluster on the grounds of Greenbriar Elementary School.

The Indianapolis Metropolitan Police Department had been called to the school about 10:40 p.m. in response to an alarm. Police checking out the building found the small plants.

Washington Township Schools said in a statement that, according to law enforcement officials, the plants didn’t appear to be cultivated.
