NORTHBROOK, Ill. - Calls are growing louder to release Rocky the coyote.
Rocky is being held inside an enclosure in Northbrook, and advocates say he is suffering.
Protesters are calling this a day of action to free Rocky.
Activists say he was originally mistaken for a German Shepherd puppy, and was deemed un-releasable.
Now, he is being held in a cage at the River Trail Nature Center in Northbrook.
Activists want him sent to a wild animal sanctuary in Colorado.
The same groups are pushing to free a large African tortoise named Spur, who is being housed at a Lincolnwood animal store.
