He was charged with criminal possession of a weapon, prohibitive use of a weapon and criminal contempt of a court.
Creedon was arrested after day-long search of his property and the surrounding area.
Suffolk Police were initially called to the house on a report that Creedon fired the weapon into the ground. After taking Creedon into custody, they spent hours searching the area.
Creedon is suspected to have been involved in the killing of Arlene and Seymour Tankleff in their Belle Terre home in 1988.
Several years ago, Suffolk County District Attorney Thomas Spota requested a special prosecutor to investigate Creedon's possible role in the Tankleff killings.
The couple's son, Marty Tankleff, was wrongly convicted of the murders and spent 17 years in prison before he was exonerated. His lawyers produced witnesses who claimed Creedon admitted to the killings in private while denying involvement publicly.
