An irate neighbor allegedly assaulted U.S. Sen. Rand Paul on Friday as the senator was mowing the lawn outside his Bowling Green, Ky., home, according to neighbors.

Kentucky State Police identified the alleged assailant as Rene Boucher, 59, of Bowling Green, charging him with intentionally assaulting Paul, causing minor injury, local law-enforcement officials told Fox News.

They said Boucher was arrested and charged with one count of fourth degree assault – minor injury. He was taken to the nearby Warren County Detention Center, where he was being held on $5,000 bail.

A second neighbor told local news station WNKY-TV that Paul was mowing his lawn around 3 p.m. when Boucher assaulted him. The neighbor said Paul's and Boucher's homes share a corner adjacent to their homes and they have been embroiled in an ongoing feud.

The assailant could face up to a year behind bars for the Class A misdemeanor. A local newspaper, the Bowling Green Daily News, reports that Warren County Attorney Amy Milliken said Boucher could face additional charges.

Officials at Paul’s Senate office say that the former presidential candidate did not suffer any major injuries.

"Senator Paul was blindsided and the victim of an assault," Kelsey Cooper, a spokeswoman for Paul, said in a statement to the Hill. "The assailant was arrested and it is now a matter for the police. Senator Paul is fine.”

Voting records from the Kentucky State Board of Election list Boucher as a registered Democrat, the Daily Caller reported. A person with his name also works as an anesthesiologist in Bowling Green.

The New York Daily News also reported that Boucher was awarded a 2003 patent for a pain relief product called Therm-a-vest, which was sold on QVC in 2005, according to a news report at the time.

A Facebook account said to be maintained by Boucher contained multiple anti-Trump postings.
