Mobster Alperon's brother: We won't attack those who killed Ya'akov

The assassination of crime kingpin Ya'akov Alperon in a Tel Aviv car bombing last month was widely believed to have rocked Israel's underworld.

There is a sweeping gag order over the investigation into the killing. But police sources have said that rival mob boss Amir Mulner is a central suspect, an assertion that has been lent weight by the support of Alperon's brother, Zalman.

Despite Zalman Alperon's harsh words for his brother's killers, he has pledged that his family is not seeking revenge for the daylight assassination.
