A 30-year-old Kamuela man has been charged after he allegedly assaulted two visitors near Hapuna Beach Park.

Herbert A.M. Lee was charged with second-degree robbery and two counts of third-degree assault. He is in custody in lieu of $7,000 bail and is scheduled to make his initial court appearance Friday.

Shortly before 4:50 p.m. Monday, police said a man and a woman of California, both 64, were exiting the park on bicycles when a truck allegedly driven by Lee drove into the park from the exit lane.

The visitors were forced to veer off the road to avoid the truck.

Police said Lee allegedly shouted at the visitors. Shortly afterward, the truck approached the visitors while they were on Hapuna Beach Road and Old Puako Road.

Lee exited the vehicle and allegedly assaulted the visitors. Police said he took the man’s cellular phone and fled when a Good Samaritan tried to intervene.

Medics responded and treated the victims at the scene.

Police arrested Lee in Kona Wednesday.
