Police in Hamilton Township, Atlantic County say they are aware of 'numerous social media posts' about the animal in the Weymouth section.
The department says officers responded to a call for a report of a black coyote or large feline in the woods on Thursday.
"After a brief search, officers located a large black dog which belonged to a local resident," the department said in a Facebook post.
Hamilton Twp. police say all of the reports appear to have stemmed from one original call or post.
"At this time, all reports/calls/posts about a black panther have been unsubstantiated," the department said.
