UPDATED with police comment and Kates’ account: Real-life and fictional police action blended on the set of NBC’s cop drama Shades of Blue Wednesday night. Details are murky but there are reports of men who interrupted the location shoot of the show in the Bedford–Stuyvesant area of Brooklyn, New York.

Word is that shots were fired, there was chaos and police were called. I hear star Jennifer Lopez had just left for the day but recurring guest star Kathryn Kates was there, with two female PAs banging on the door of her trailer as they were allegedly being chased by the perpetrators. (You can read her account below).

There are conflicting reports about gunfire in the streets where the series was filming. I hear police or security quickly took control over the situation. While a number of cast and crew members are shaken, sources close to the production say that everyone on the show is safe. When reached for comment, NYPD Lt. Thomas Antonetti told Deadline that they had no confirmed reports of a shooting and that no 911 call was made.

Shades of Blue, an NYPD crime thriller starring Lopez, Ray Liotta and Drea de Matteo, is currently filming its second season for a midseason premiere. Lopez plays Harlee Santos, a single-mother NYPD Detective, who is forced to work in the FBI’s anti-corruption task force, while dealing with her own problems.
