A Scottsdale man is accused of trying to hire undercover police detectives to extort or harm a real estate mogul who won a $1.2 million lawsuit against him.
Authorities say 46-year-old Mikhail Kordonsky is being held on suspicion of conspiracy to commit first-degree murder.
Kordonsky's bond was set at $500,000 at his initial court appearance Friday. He doesn't have an attorney yet.
Court records show Kordonsky wanted to get revenge against an unnamed head of a commercial real-estate company.
Police say Kordonsky spoke of plotting to kidnap the man, beat him with a bat and shoot him in the back of the head if he didn't pay $10 million in diamonds because they're untraceable.
Investigators say Kordonsky claimed connections to a mobster who's serving a federal prison sentence in Arizona.
