May 4, 2006 -- Disturbing videos unmasking the raw hostility between warring Hasidic factions - including shots of a man spraying another with a fire extinguisher - have been handed over to cops and the Brooklyn DA, The Post has learned.

The footage was taken Oct. 25 at the Williamsburg synagogue of the late Grand Rebbe Moses Teitelbaum, who died last week.

They surfaced as the DA vowed more arrests would follow this week's bust of several men charged with April violence at the synagogue.

According to a close associate of Zalmen Teitelbaum - whose followers are fighting those of his older brother Aron for control of the Satmar sect - the October video shows an Aron supporter opening fire with the extinguisher.

Another clip shows bouncers punching and shoving Hasids trying to clamber into the synagogue. Each side claimed the guards were hired by the other.

Still another shows an alleged Aron supporter hurling a prayer book into a roiling crowd, according to the source.

"The police have it; the DA has it. These are the things they are investigating and they say they are going to take action," the Zalmen source said. "We'll see."

Aron's supporters say they've provided cops with proof of their innocence.

The video surfaced as District Attorney Charles Hynes laid down the law regarding the religious feud.

"It has to be made clear to the leadership of both sides that if you come to commit crime in the county, you will be arrested," he declared.

On April 22, a fistfight broke out in the synagogue when - according to Aron supporter Abe Rubin - three Zalmen followers at the congregation Yetev Lev jumped him, broke his finger and stole his fur hat.

"I went in to pray," Rubin told The Post. "I went into the synagogue and it didn't take five minutes and I was beaten."

Two men turned themselves in at the 90th Precinct yesterday in connection with the brawl - Mendel Epstein and Abe Braun. A day earlier, Abe Mendlowitz surrendered on charges of assault. All three were issued desk appearance tickets and released.

Mendlowitz and Braun are already on probation for assault in a previous rumble with Aron supporters.

But Zalmen supporters like Martin Kahan argued Rubin is a "well known troublemaker" and blamed the October brawl on him. Rubin denied the allegation.
