Tyson Foods' board of directors is overseeing a "thorough review" of the recent arrest of Chief Financial Officer John R. Tyson on charges that he trespassed at a young woman's house while intoxicated, Chief Executive Officer Donnie King said on Monday.

John R. Tyson, great-grandson of the meat company's founder, apologised during a quarterly earnings call for his November 6 arrest for criminal trespassing and public intoxication in Fayetteville, Arkansas.

"I'm embarrassed and I want to let you know that I take full responsibility for my action," said Tyson, 32. "This was an incident inconsistent with our company values, as well as my personal values."

A college-age female was alarmed to have found Tyson, whom she did not know, asleep in her bed on returning home, according to a Fayetteville police report.

The police report cited "Tyson's unlawful presence in a house, where he was not invited, paired with the odor of intoxicants, and his general demeanor when confronted by uniformed officers."

John R. Tyson is the son of the chairman of the company’s board of directors, John H. Tyson. The board is independent, King told analysts on the earnings call. He did not give details about the review.

"Like John, the company takes this matter seriously," King said. "I'm confident in this independent process."
