A man was arrested after police found assault rifles, instructions on how to make bombs and a trove of Nazi paraphernalia at his home in New York.

29-year-old Edward Perkowski faces weapons and drug charges after police also found $40,000 in cash, marijuana and hallucinogenic mushrooms at his house in Long Island.

Authorities said his arrest meant they had “neutralized a clear public threat”.

His 25-year-old brother, Sean, who lives in the same house was also arrested for an outstanding bench warrant that was unrelated.

“Today’s search warrant might have prevented a deadly, violent incident, like the one we recently saw in Orlando,” the Suffolk County police commissioner, Timothy Sini, said at a news conference, according to the New York Times.

He added the brothers “clearly subscribed to a hateful ideology”, with an illegal arsenal “at their fingertips”.

The discovery comes just days after a 29-year-old gunman who pledged allegiance to Isis burst into a gay nightclub called Pulse in Orlando and shot dead 49 people and injured 53.

The trove of weapons in Long Island included handwritten bomb-making instructions, six assault rifles, a handgun, a shotgun, four rifles and a stun gun, and some of the guns had high-capacity magazines, said Mr Sini.

The weapons and a leather-bound binder, described as a “racist manifesto”, were lined beside a framed picture of Adolf Hitler and flags with swastikas.

The Brookhaven town supervisor, Edward Romaine, said the brothers' house was infected with the “disease called hate”, and authorities “want to stop hate in this country”.

A third brother denied that Mr Perkowski was a Nazi or neo-Nazi, as reported by CBS news.

A friend, who only identified himself as Bob, told the network: “What the hell are they talking about, they’re going to plan some attack?! I’ve known them my whole life. They’re not going to do anything.”

Neighbours had said they had dealt with trouble “for years” and made multiple complaints of alleged assault, traffic, noise and partying.

The incident also comes just a few days after a man from Indiana, James Howell, was arrested after driving nearby the Los Angeles gay pride march with a stash of weapons in his car.
