A dispute between boat owners at Sand Island led to the arrest of a man suspected of attempted murder.

Police said one man, 48, got angry about a 23-year-old man anchoring his boat near the Sand Island marina about 9:30 p.m. Thursday.

The first man confronted the second man and assaulted him using what police described only as a dangerous instrument, detectives said.

The victim was treated for his injuries at a hospital and released, police said.

The suspect was arrested at the marina FRiday and was being held pending charges of second-degree attempted murder, second-degree assault and fourth-degree criminal property damage.
