The 31-year-old Deveaux, a veteran of 31 NHL games with the Toronto Maple Leafs and the New York Rangers, attacked Vasteras IK captain Per Helmersson, who had his back to Deveaux, when the Canadian whacked him on the leg.
Deveaux, who played with Swedish league club Rogle BK, had his contract terminated and a Swedish prosecutor ordered his arrest.
He admitted he is not proud of what he did, but added he's "not sorry for protecting myself when no one else would."
Deveaux claimed that he was "brutally hit" during the playoffs in Sweden and says "the hit affects me every day, even five weeks later."
"I was checked from behind by Per Helmersson," Deveaux said. "He hit me hard — right in the numbers, where we are told never to hit — and I was thrown into the boards."
Deveaux said he "received threats that I would be a target again," but did not say who threatened him. He also said he was told to protect himself but didn't expand on the statement.
He has appealed the Swedish Ice Hockey Association's decision to suspend him, and says he has instructed his lawyer to cooperate with the prosecutor who he says "has not taken me up on my offer."
Deveaux said he called the news conference because "you've been told a partial story from a biased source.
"My reputation is not who I am," he said. "I don't want sympathy. I want fairness."
