Sausalito police arrested a man early Thursday morning on suspicion of assaulting a man with a frying pan on a vessel in Richardson Bay.
Police responded around 1:15 a.m. to a phone call about a man possibly using a metal baseball bat to assault a woman on a vessel anchored around 100 yards from the Turney Street boat ramp, Capt. Bill Fraass said.
During the call, officers heard a male on another anchored vessel in the area talking about being struck with a frying pan, Fraass said.
While responding in a police patrol boat to the anchored vessels, officers saw a vessel sailing away from the scene and stopped it in the area of Schoonmaker Point. They contacted Halsey Dunman, 65, an anchored out resident of Sausalito, and a 60-year-old woman Dunman was dating, according to Fraass.
Dunman and the woman had been on the woman's brother's vessel where an argument occurred. Dunman allegedly struck the woman's 56-year-old brother in the head with a frying pan multiple times and took away the woman's phone when she tried to call 911, Fraass said.
The woman's brother came ashore while police were interviewing Dunman and he was taken to a hospital by the Southern Marin Fire Protection District.
Dunman was arrested on suspicion of assault with a deadly weapon, domestic battery and preventing someone from calling 911 and was booked into Marin County Jail.
