Police in Jerusalem on Tuesday arrested the groom from a wedding three weeks ago, after video from the event was leaked to the media showing Jewish extremists appearing to celebrate the deadly Duma arson while waving weapons.

Aside from the groom, three other participants in the wedding were also arrested, and will be brought on Wednesday for a hearing on an extension of their arrest.

Earlier on Tuesday, the police detained a resident of Kfar Tapuach in Samaria who was videotaped dancing at the wedding with a gun in his hand.

In the footage dozens of men and boys can be seen dancing while waving guns and knives. One masked individual can also be seen carrying a mock molotov cocktail and a picture of the Arab baby killed in the Duma arson attack, and at one point, the masked individual can be seen stabbing the picture.

Attorney Itamar Ben-Gvir argued that the weapons seen passed around among minors in the video were toy guns, and "even if this was a tasteless act, there is no criminal offense in dancing like this."

Regarding the wedding, Tzfat (Safed) Chief Rabbi Shmuel Eliyahu on Sunday claimed that the Israeli Security Agency (ISA) "cooked up" the incident to cover up public outcry, over allegations of brutal torture against Jewish suspects being held in the Duma case.

Rabbi Eliyahu noted on past cases of reported entrapment by the ISA, and emphasized that the one person present at the wedding who held up a picture of the Arab baby has yet to be identified, arguing he may have been planted there to negatively portray the "Hilltop Youth."

Lending weight to the rabbi's questions are statements by the groom's parents, who claimed the wedding was hijacked, that those videotaped dancing with the picture were not invited guests, and that their son did not recognize them.
