In a closed-door hearing, a Tel Aviv judge ordered three of the suspects, including the alleged shooter, held in custody for 11 more days, The Jerusalem Post reported Thursday.
Charges against the three suspects include two counts of murder and 11 counts of attempted murder.
The fourth suspect has been charged in a crime police believe to be linked to the shooting, although officials said he didn't take part in planning or carrying out the shooting.
The suspect is a prominent member of the LGBT community, which appeared to rule out a long-held theory the attacks were motivated by hate.
The motive for the killings, police said, was revenge against a member of the gay community who one of the suspects thought had wronged him.
Police said the three main suspects also were wanted for dozens of break-in of cars, drugs and weapons charges and arson.
The judge placed a gag order on releasing most of the details surrounding the arrests.
