A Lafayette man arrested Friday on one count each of attempted second-degree murder and second-degree battery is accused of stabbing another man and, in a separate incident, beating his girlfriend.

Hamp Michael Penson, 57, is accused of stabbing a 30-year-old man three times in the chest and legs Wednesday in the 300 block of Madison Street, said Cpl. Paul Mouton, Lafayette Police spokesman.

The victim told police he was pulling into a driveway when Penson parked a vehicle behind him, came out wielding a knife and then attacked him in his car, Mouton said.

The motive behind the stabbing is under investigation, Mouton said.

The second-degree battery count stems from a Monday incident involving Penson’s girlfriend, who suffered moderate injuries, Mouton said. Penson was also booked on a count of false imprisonment in the domestic disturbance.

Penson remained in the Lafayette Parish Correctional Center on Friday afternoon without bond.
