Grants Pass man accused of assaulting brother with samurai sword arrested in Beaverton

A Grants Pass man on the lam after allegedly assaulting his brother with a samurai sword last month was arrested Thursday by Beaverton police, the Oregon State Police reported.

Police believe Preston James Sweaney, 23, attacked his younger brother, 21-year-old Nathaniel Sweaney, after an argument in a motor home on Northwest Highland Drive in Grants Pass turned physical shortly before 2 a.m. Nov. 15.

Nathaniel Sweaney suffered lacerations to his side and left arm. Another relative, 18-year-old Christian Burnison, received a minor cut on his hand while trying to intervene. Preston Sweaney then fled the scene, police said.

Preston Sweaney was arrested at about 2:15 p.m. Thursday in the 14000 block of Southwest Sixth Street in Beaverton, according to Sgt. Jeff Fitzgerald of OSP's Criminal Investigations Division.

Sweaney was lodged in the Washington County Jail on a felony drug warrant out of California, and a misdemeanor warrant from Curry County, according to OSP. Charges are pending in Josephine County for second-degree assault and unlawful use of a weapon. (Information on warrants corrected from a previous version.)
