Senior crime figure Amir Mulner, a prime suspect in last weeks car-bomb assassination of mob kingpin Ya'acov Alperon, was arrested on Wednesday evening. Mulner was taken into custody during a raid on a Ramat Gan apartment, together with 16 other suspects, police said. A police source told The Jerusalem Post that despite the suspicions hanging over his head, Mulner's arrest was a "routine operation by the Tel Aviv Police Central Unit." A gun and a silencer were recovered during the raid. Police would examine whether Mulner was connected to Alperon's killing, the source said. Mulner, who is an explosives expert, was stabbed in the neck by Alperon's son Dror during an altercation with Alperon senior at a Herzliya hotel in 2006. Soon afterward, police arrested Mulner in Baka al-Gharbiya with bombs in his possession.
