A brawl broke out at a Jerusalem synagogue between some of the guests and a number of waiters towards the end of the wedding of Chief Sephardic Rabbi Shlomo Amar's daughter Ayala.
Police arrested two of the guests, and their custody will be extended by the court on Thursday.
The police's investigation found that at around 23:30, one of the guests attacked an Arab waiter and broke a bottle over his head. Shortly afterwards, another waiter accidentally touched the shoulder of another guest, who responded by allegedly striking the waiter.
A brawl broke out and one of the managers called the police, who arrested two of the guests after separating between them and the waiters.
One of the waiters was lightly injured, but refused to be taken to receive medical treatment.
The wedding was attended by, among others, President Moshe Katsav. The ceremony was conducted by Shas spiritual leader Rabbi Ovadia Yosef.
Rabbi Amar's daughter hit the headlines previously after meeting a teenage boy in an internet chat room.
The chief rabbi's son, Meir, kidnapped the teenager from his home, where he interrogated him over relations with his sister.
Last Week, the Tel Aviv District Court sentenced the chief rabbi's son to two years eight months prison time, in the context of a plea bargain.
The rabbi's wife, Mazal, admitted she distorted a report on an attack on the minor, but was not convicted.
