Police were set to ask to extend the remand of underworld kingpin Yaacov Alperon on Tuesday, following his surrender to police on Monday after a week of hiding underground. On Monday night, Alperon was interrogated and relayed his version of the sequence of events that reportedly led to the stabbing of fellow underworld figure Amir Mulner by Alperon and his son, Dror. Alperon maintained that he was innocent while speaking to Channel 10 news on Monday evening. Police were still searching for Dror Alperon on Tuesday morning. Police officials said that if he did not turn himself in soon, it would add an additional count against him - evasion of the law.
