According to The New York Post, former ANTHRAX singer Dan Nelson has been arrested for allegedly beating a 74-year-old man inside a Queens, New York hotel last month.

The 43-year-old musician is accused of repeatedly punching the older man in the face on August 30 at the Aloft New York LaGuardia Airport hotel in East Elmhurst.

The alleged attack happened after the victim asked Nelson a question that apparently set the singer off.

"He just goes bananas," a family member of one of the older man's companions told Patch. "He knocked the old guy down."

After turning himself in at the 115th Precinct at 8 a.m. Wednesday, Nelson was charged with assault, assault with intent to cause physical injury and harassment.

Nelson was officially in ANTHRAX for nearly two years — from late 2007 until July 2009 — during which time he recorded an early version of the band's "Worship Music" album. After Nelson and the group split, the LP was temporarily shelved while ANTHRAX figured out its singer situation. Once Joey Belladonna came back into the lineup in early 2010, ANTHRAX went back into the studio and reworked the songs on "Worship Music" with Joey's vocals.

Nelson in 2012 settled a lawsuit he filed against ANTHRAX over the fallout from his departure from the veteran metal group. Details of the settlement were not made public.

The singer filed a lawsuit in November 2011 claiming that Charlie Benante (drums), Frank Bello (bass) and Scott Ian (guitar) falsely stated in "numerous interviews" that he had "abruptly resigned" after getting sick, forcing a cancelation of a tour. The $2.65-million suit also alleged that Benante told BLABBERMOUTH.NET that Nelson "was a bully."

The Long Island native said his ex-bandmates' "intentional defamation" caused him a loss of income and damaged his reputation.

Before reaching the deal, ANTHRAX attorney Brian Caplan told the judge that Nelson had been offered a "fairly small dollar amount" and co-authorship of eleven ANTHRAX songs that the band recorded for "Worship Music", according to the New York Daily News.
