Tel Aviv District Court remanded the three suspects in the murder of Arik Karp on Thursday for the duration of the court proceedings against them, Army Radio reported.
Karp was beaten to death on the Tel Aviv promenade while sitting with his family in August.
The judge said that there was pathological evidence that Karp died of wounds inflicted during the alleged attack. The judge also rejected the defense's assertion that something happened to Karp between the time that the defendants left him and his 'fall' into the sea, in which he was later found.
Four others - Fadi Jaber, Fuad Musa, Mahmud Ades and Or Levy, an IDF soldier - were charged with failure to prevent a crime and violation of the obligation to come to the aid of someone in danger.
