In a series of chilling calls to police, a former US dressage Olympian told a 911 dispatcher that he was at “war” with the award-winning equestrian he allegedly shot at nearly point-blank range.

Michael Barisone called 911 on his “clients” in the week leading up to the Aug. 7 shooting at his 53-acre farm in Morris County, New Jersey, according to NJ.com, which obtained the partially redacted recordings.

In them, the member of the 2008 Beijing Summer Games squad accused Lauren Kanarek and her fiancé, Robert Goodwin, of trespassing, failing to pay rent and harassment.

“They’re causing trouble, they’re stirring s— up. They’re here in our private horse facility, and these people need to be warned,” Barisone said on July 31. “This is a war and it’s going to be dealt with right now. I’ve had enough of these people. I need them gone.”

Barisone told the dispatcher that Kanarek and Goodwin were living at his sprawling dressage facility without a lease and without paying rent.

“They are clients who have become a menace to us,” he said in the July 31 call. “These people are destroying our lives. These people are insane.”

He also said the couple had been “causing us hell” by allegedly squatting at his Hawthorne farm.

“We used to live there but we left because we’re in fear of them,” he said.

The next day, he dialed 911 again, to complain that Kanarek, 38, was walking down the driveway while screaming on the phone with her father.

“This is a situation going from bad to worse,” Barisone said.

He also told police in an Aug. 3 call that he and his family were “in fear for our lives” after Kanarek posted on Facebook that she is “not responsible for anything my other personalities do when they’re threatened.”

Barisone, 54, is charged with attempted murder and weapons possession for pumping two bullets into Kanarek’s chest, leaving her in grave condition.

Tensions between the international dressage competitor and the couple — who were all at one point friendly — peaked after Kanarek accused Barisone of child abuse.

Barisone was interviewed by investigators with New Jersey’s child welfare agency, the Division of Child Protection and Permanency, just “moments” before the alleged shooting, his lawyer said.

In the week leading up to the attack, Kanarek also called police to report a “blacked-out SUV with some guy smoking a cigarette in the front who I’ve never seen before.”

“Except for last night at 3:15 in the morning, and we overheard them talking about like getting guys to like hurt us, kill us or whatever,” she told the dispatcher, adding that she felt her life could be in danger.

Meanwhile, in Barisone’s final call to police three days before the shooting, he can be heard arguing with Goodwin.

“I’m taking my life back,” Barisone told the dispatcher.
