PONTIAC, Mich. — A 25-year-old Oakland County man told police that he was stabbed after finding his wife in bed with her own father, WWJ reports.

It happened just after 3:30 a.m. Saturday when the man arrived at his home on West Rundell Avenue to find his wife, completely naked, in bed with her father, police say.

The man then reportedly woke his father-in-law up and the two began to fight.

Police say the father-in-law, identified by authorities as Henry Allen Michael of Detroit, allegedly stabbed the younger man in his back with a knife. He then fled the scene in the victim’s car.

The victim was taken to McLaren Hospital with a non-life threatening stab wound.

Authorities later spoke to the 24-year-woman who said she was out drinking with her father then passed out when they returned to her house. She says she did not know what had happened until her husband woke her up, police say.

The woman said she thinks she was sexually assaulted and insisted on being examined at the hospital.

Michael, who was staying at the couple’s home after being released from prison, was later arrested.

According to Oakland County authorities, Michael’s criminal history includes a 1992 robbery for which he was found guilty, sentenced to 20 years and released in 2012. Then, in March of 2015, Michael pleaded guilty to assault with a dangerous weapon.
