The latest twist in the probe of the death of Hamas co-founder Mahmoud Mabhouh involves a forged passport of an Israeli soldier who fell in the Yom Kippur War, The Wall Street Journal reported.

The forged British passport holder’s name was Christopher Lockwood, leading investigators to believe they had a hot lead towards solving the mystery of who was behind the assassination. Mossad agents have been widely accused of forging more than two dozen passports, but there is no proof that they murdered the terrorist.

The Journal reported that authorities concluded that Lockwood had changed his name to Yehuda Lustig in 1994, but it turns out that the identity was a ruse, because Lustig was killed in 1973 in the Yom Kippur War.

Dubai investigators are back to square one, and eight months after Mabhouh’s mysterious death, Dubai officials are no closer to solving the case.

"The longer these investigations go on, the more enthusiasms dwindle and the more time for a security service to cover tracks and bury things," according to a Journal source, Nick Day, “a former operative in the U.K.'s MI5 security service who isn't involved in the probe.

The newspaper noted that Israel works closely with the United States in fighting terrorism, a fact that may be hampering American cooperation with Dubai police.
