NASHUA, N.H. (CBS Hartford) – A police commissioner resigned from his position after he assisted a New Hampshire state representative who ran over and killed several ducks in December.

Nashua Police Commissioner Tom Pappas wrote a letter to Gov. Maggie Hassan citing that he regrets his role in the incident, WMUR reported.

“I deeply regret my part in the events of December 23, 2013, and apologize to you, the Nashua Police Department and the public for the disruption that has occurred as a consequence of them,” Pappas wrote in the letter, according to WMUR.

State Rep. David Campbell ran over and killed several ducks outside of the Crowne Plaza Hotel in December and left the scene before police arrived. Pappas called the police department asking if it was alright if Campbell came in for questioning the next day because they were friends and the police agreed.

The Attorney General’s Office is now investigating whether further action will take place.

“I am determined to move forward productively and positively by cooperating in any manner necessary with the investigation being conducted by the Attorney General’s Office,” Pappas explained in his resignation letter.

Nashua Alderman Ken Siegel agrees that Pappas did the right thing by stepping down and that Campbell should do the same thing.

“I just think he was trying to help a friend, and unfortunately he made a bad decision, and now he did the honorable thing and he resigned,” Siegel told WMUR. “Not only were his (Campbell’s) actions the instigation for all of this, but he’s brought a good man down.”

Witnesses to the incident said that Campbell was drunk, but charges weren’t filed, WMUR reported. He did pay a fine later.
