The Jerusalem District Court has permitted for publication further details about the investigation over the murder of 16 year-old Mohammed Abu-Khder, including background on the suspects.
IDF Radio reports Wednesday night that three of the suspects were involved in other serious crimes before the murder; the remaining three were "less involved" in burning the teen alive.
Some of the suspects have been sent for psychiatric observation, the statement continued, adding that investigators were also determining whether the suspects had links to terror, criminal, or racist organizations.
The Israel Security Agency (ISA) confirmed that three suspects have finally been allowed to meet with legal representation, although three have still been barred from legal counsel.
Earlier Monday, police reported that three out of the six suspects arrested on Sunday confessed to the murder of the Arab teen, and even re-enacted the crime for investigators.
Abu Khder's body was found in the Jerusalem Forest Wednesday, sparking rioting across Jerusalem and nationwide.
Police suspect that the crime was nationalistically motivated, allegedly as a "revenge crime" for the murders of Israeli teens Naftali Frenkel (16), Gilad Sha'ar (16), and Eyal Yifrah (19).
An initial pathologist's report, issued from Palestinian sources, stated that Abu-Khder was burned alive, with the teen suffering from severe burns on 90% of his body.
The suspects arrested for the murder are Jewish; some are minors. They are residents of Jerusalem, the community of Adam north of Jerusalem, and Beit Shemesh.
