Internal Security Minister Gilad Erdan (Likud) on Friday morning spoke about the investigation of the lethal Duma arson in July, after it was published on Thursday that several Jewish youths have been arrested on vague suspicions of involvement. 

Erdan admitted that the security sources do not have enough evidence to put the Jewish youths on trial.

"There are not many investigations that merit such high prioritization like the investigation of the murders that happened in the village of Duma, and still the general security services and police have advanced in this investigation," Erdan told Army Radio.

"We are doing everything so that we will also have evidence to allow a trial and a submission of indictments," added the minister, admitting to an abject lack of evidence against the arrested youths.

Erdan's comments come after Attorneys Adi Keidar, Chai Haber and Itamar Ben-Gvir held a press conference on Thursday night to complain about the "heavy-handed, violent" investigation that they argue has breached the basic rights of their clients.

The suspects have not been allowed to consult with their lawyers or speak with their families, despite no charges being submitted against them.

Testimony has come forward of Israel Security Agency (ISA) agents brutally beating the suspects during their arrest and hiding video evidence of the assault, and arresting a nurse who is the sister of one suspect while she was working at a hospital. The father of one suspect testified that his son was in Tzfat (Safed) at the time of the attack together with another suspect.

Keidar noted that the police admitted in court that they presented false figures in the initial arrest warrants, and despite that the court accepted what the attorney termed an attempt to make the legal defense "fail."

ISA is trying to get "confessions by force," accused Haber, saying, "we receive indications of lengthy hours of interrogation, sometimes beyond what the law allows, detainment in substandard conditions, not giving required medical treatment, and not giving food in a fixed and appropriate manner."

Ben-Gvir said his client was beaten and wounded in his arrest according to testimony by the suspect's wife, and noted with concern that the suspect was not brought to the court on Thursday in an apparent attempt to hide his medical condition.

"We are not in Argentina!," he exclaimed. "It can't be that in the state of Israel they make people disappear in the basement of the general security services headquarters and no one opens their mouth."

Criticism over the handling of the case gained steam after Defense Minister Moshe Ya'alon (Likud) publicly announced in September that the identities of the arsonists were known. However, just a month later in October, Prime Minister Binyamin Netanyahu admitted the arsonists - or even proof - in the case hadn't been found yet.

Some have speculated the investigation is following the wrong lead, given reports and unusual circumstances at the scene of the crime that would indicate the arson may have been an inside job committed by feuding residents of the Arab village. Israel has reportedly left investigation of the Arab village to the Palestinian Authority (PA), instead chasing the "Jewish terrorism" angle based on Hebrew graffiti found at the site.
