Police say they're investigating after a noose was found hanging between two tree limbs in central Philadelphia.

Authorities say they responded to a report of the noose around 10 a.m. Friday, but noted that it doesn't appear to be targeted toward a specific person. A spokesman said the department is trying to get surveillance footage of the street, located several blocks from the toney Rittenhouse Square neighborhood.

Mayor Jim Kenney issued a statement condemning the noose and asking witnesses to come forward with information.

The incident comes after the U.S. Mint in Philadelphia put an employee on leave after a noose was found on the chair of an African-American colleague.
