BROOKLYN - An investigation is underway after a Brooklyn teenager was killed by his remote-controlled helicopter.

According to police, 19-year-old Roman Pirozek was flying his model helicopter at Calvert Park on Shore Parkway and Bay 44th Street in Gravesend Thursday afternoon when it malfunctioned.

Officials say the chopper suddenly boomeranged back at Pirozek, slashing him in the head. He was pronounced dead at the scene due to severe head trauma.

Brooklyn Councilman Domenic Recchia is now trying to postpone flying electronic planes until it’s determined what rules and regulations can be put in place to prevent another similar incident.

Pirozeck was a remote-controlled helicopter enthusiast and a part of the Seaview Rotary Wings Club. He graduated from the High School for Construction Trades, Engineering and Architecture in Queens.
