Update: from the Jerusalem Post:

Prime Minister Benjamin Netanyahu was interrogated under caution today on suspicion of alleged corruption. The interrogation lasted for three hours and was conducted at the prime minister's residence in Jerusalem. Netanyahu is expected to be questioned at least once more prior to the completion of the investigation.

Originally:

As the Obama administration shunned Israel last week, we warned that police were calling on Israeli Attorney General Avichai Mandelblit to allow them to open a full criminal investigation against Prime Minister Benjamin Netanyahu. Today, as Channel 2 reports, Israeli police entered Bibi's home for questioning. The prime minister was quick to react, blasting "don't celebrate too soon over corruption probe."

As we detailed last week, on Monday, December 26th, Israeli police announced that they are absolutely convinced that a criminal investigation will be opened in the next few days due to new documents that were recently received in a special inquiry that began about 9 months ago.

The offenses that Netanyahu allegedly will face will be bribery and aggravated-fraud. In June it was reported that police had recently started their secret investigation, with demand that no details be leaked to the media. Attorney General Mandelblit also allegedly instructed employees in the state prosecutor’s office to investigate allegations that Netanyahu accepted 1 million euros (about $1.1 million) from accused French fraudster Arnaud Mimran in 2009. Earlier in December, in an apparently unrelated case, there were calls for the Netanyahu to be investigated for his role in a Defense Ministry deal to purchase submarines from a German company that is partly owned by the Iranian government. The affair overtook public debate in Israel last month, as accusations came about that the Israeli prime minister may have been financially swayed in the decision by his personal counsel David Shimron, who himself had ties with the submarines’ builder, ThyssenKrupp. The purchase was opposed by sectors of the defense establishment, including former defense minister Moshe Ya’alon. A spokesman for Netanyahu defended the Prime Minister by telling The Times of Israel, “This is absolutely false. There was nothing and there will be nothing.”

And today, as The Telegraph reports...

Benjamin Netanyahu, Israel’s prime minister, is being questioned by detectives on suspicion of illegally accepting valuable gifts from prominent businessmen in a scandal that is roiling Israeli politics. Police officers came to the prime minister’s official residence in Jerusalem on Monday evening to question him about claims that he took designer suits and overseas trips his son from at least two businessmen. Mr Netanyahu denies any wrongdoing and has not been charged but the criminal investigation into him is one of several probes swirling around him and his family. His wife, Sara, was questioned by police in a different case just weeks ago. Police probes against politicians are common in Israel and Mr Netanyahu’s predecessor, Ehud Olmert, is in prison for corruption. Ariel Sharon was questioned by police over accusations he accepted bribes but the case was dropped and he was never charged.
