A 65-year-old Eugene man was attacked at random Sunday afternoon on the street in the Whiteaker neighborhood.

The victim was standing at the corner of West Sixth Avenue and Monroe Street when Sean Diamond Mulroy, 29, charged him and knocked him to the ground, according to Eugene police.

Once on the ground, Mulroy allegedly started beating the victim.

Mulroy and the victim did not know each other, police said.

Police said Mulroy then got up and punched a car parked nearby, leaving dents in the hood, before fleeing north on Monroe.

The victim was taken by an ambulance to a hospital. His condition is not known.

Officers found Mulroy near West Fourth Avenue and Madison Street and arrested him on suspicion of second-degree assault and second-degree criminal mischief. Formal charges are expected Tuesday afternoon.
