BETHPAGE, N.Y. — A firefighter has been arrested on arson charges in connection with a spate of fires in Bethpage, Long Island.

Christopher Cordeiro, 20, is to be arraigned on Monday in First District Court in Hempstead, Nassau County police said. Information on his lawyer wasn't immediately available.

Police said Cordeiro is a member of the Bethpage Fire Department. They say he used a Molotov cocktail to set fire to a sump in June last year. He's also accused of setting fires to a dumpster in March and an abandoned house, a wooded area and a shed in August. No injuries were reported.

Police said Cordeiro was arrested at the Bethpage fire house.

Cordeiro is accused in the following incidents:

June 25, 2017 – Across from 25 Arthur Avenue – Molotov cocktail fire in a sump

March 1, 2018 – 67 West Millpage Drive – Dumpster fire

Aug. 5, 2018 – 285 Stewart Avenue – Abandoned house fire

Aug. 10, 2018 – Next to 96 Broadway – Wooded area fire

Aug. 19, 2018 – 121 North Hermann Avenue – Shed fire

The fire department to which Cordeiro belongs released this statement:

"The Bethpage Fire Department responded to a fire of suspicious origin on August 10, 2018. Based on this incident, fire department officials reviewed their records and determined that a pattern had developed indicating that they may be dealing with a serial fire setter. A fire that occurred on August 19, 2018 reinforced their belief prompting the Fire Department to request an investigation of the fire. The Nassau County Fire Marshal’s office responded immediately and received information from the Fire Department that aided in their investigation."
