BROOKLYN - The teenager accused of starting a Coney Island fire that killed an NYPD officer was arraigned today.

Marcell Dockery is charged with second-degree murder and first-degree assault in an April 6 blaze that resulted in the death of Officer Dennis Guerra.

The 16-year-old had admitted to sparking the flames, saying he was "bored." However, his defense attorney says he's denying the initial confession and claims he was forced to admit to the crime after an interrogation.

Guerra died in the hospital three days after he and his partner, Rosa Rodriguez, rushed into the burning building. She remains hospitalized.

Dozens of fellow police officers were in court for the arraignment, along with families for both Dockery and Guerra.

Guerra leaves behind his wife and four children.

Dockery was remanded without bail and he is due back in court on May 29.
