One man went to extreme measures to express his disapproval of the Thunder trading All-Star Paul George.

Oklahoma City police are investigating a potential death threat from an angered fan who severely disagreed with sending George to the Clippers in a deal thats put him alongside Kawhi Leonard. A search warrant says that a man left two voicemails threatening the Thunder’s front office, head coach Billy Donovan and general manager Sam Presti.

The man, who identified himself as a resident of Virginia, said that he’d “blow things up” if he ever went to Oklahoma.

“Y’all traded Paul George but kept Raymond Felton. You kept Andre Roberson. Do y’all not love Russell Westbrook?” the man said, according to a transcript of one of the voicemails obtained by KOCO5. “I hope he kill everybody. I want to kill everybody.”

In the voicemail, the deranged fan claimed that he didn’t care if the team reported him to the authorities. He then went on to insult Donovan, claiming that he’d beat everyone who worked for the Thunder, according to court documents.

Reports say that the man left a second voicemail shortly after, expanding his threats to Presti and his family.

A search warrant gave police the green light to investigate a cellphone and where the call originated.

The Thunder released an official statement saying, “We defer to the authorities and they can handle the situation as they see fit.”

After dealing George, the Thunder completed their teardown by sending Westbrook to the Rockets for Chris Paul and draft picks. The Thunder reportedly attempted to trade Paul to the Heat, but now it seems the nine-time All-Star will start the season in Oklahoma City.
