The NYPD is investigating a possible hate crime at the Bronx headquarters of the city's Parks Department.

A worker found a small black doll hanging from a metal chain shaped like a noose Tuesday morning. As of Wednesday, no arrests had been made.

Police said the investigation is continuing and so far there's no evidence of ongoing disputes between employees or previous incidents of a similar nature at the facility located at 1 Bronx River Parkway.

In a written statement, the Parks Department said it immediately reported the incident to the NYPD and its fully cooperating in their investigation.

"The Parks Department does not tolerate prejudice of any kind and we are committed to maintaining a safe and respectful workplace environment," Commissioner Adrian Benepe said in the statement.

According to statistics released earlier this year by the FBI,  hate crimes in New York City rose 28 percent in 2010 compared to the prior year. The New York State Division of Criminal Justice Services found in 2010 that there were 39 reported anti-black hate crimes — only one of those was reported in the Bronx.
