Shalom Avitan is believed to be affiliated with Mosley's crime syndicate, and the assassination was planned amid ongoing conflict between the organizations. Recently, it was suspected that criminals from Haya's organization threw grenades at Avitan's residential building in Tel Aviv.

Because he was trying to get revenge on Haya, it is possible Avitan was sent by senior criminals from him to carry out the assassination. Avitan, 37, was arrested last Wednesday. Federal police in Malaysia reported that they arrested him at a hotel in the capital's prestigious Jalan Ampang district.
