A man has been arrested in a nunchucks attack on two neighbors over an ongoing dispute in Larimer County, authorities said Tuesday.After a five-hour standoff with deputies, Eric Leon Glukowsky, 31, surrendered early Tuesday, said Larimer County sheriff's spokesman John Schulz.Glukowsky was arrested for investigation of felony assault and was being held at Larimer County Jail.Deputies received a call at 12:43 a.m. about an assault in the 4000 of Goodell Lane, southwest of Fort Collins. Arriving deputies found two individuals who had been injured by nunchucks, a martial arts weapon which is classified as a deadly weapon, Schulz said.Glukowsky barricaded himself in his apartment and refused to come out, Schulz said.Deputies made repeated and unsuccessful attempts to call Glukowsky and negotiate his surrender. They finally used a foam baton to break a window in Glukowsky's apartment so they could talk with him, Schulz said.They finally persuaded Glukowsky to surrender without incident at about 5:45 a.m.Deputies believe the assaults was triggered by an ongoing dispute between neighbors, Schulz said. Schulz would not say what the dispute was about.The victims were transported to Poudre Valley Hospital, treated for lacerations and later released, he said. They have not been identified.
