Toms River police responded to a fire behind a residence on Bay Stream Drive Sunday morning.
An investigation found that a dock behind the residence was on fire.
The fire was apparently ignited by fireworks, according to Toms River Police Chief Michael Mastronardy.
The fire was extinguished by The Silverton Fire Company.
The homeowner, who reported some friends had set off fireworks earlier in the evening, was issued a citation for illegal fireworks, Mastronardy said.
Officer Ken Thomas and Jason Putkowski were the responding officers.
