A heavy police presence descended on a neighborhood west of the University of Oregon, where officers were seeking the suspect in Tuesday morning's shooting near a school.

After a nearly four-hour siege outside a home on Mill Alley, police said shortly before 10 p.m. that the 17-year-old shooting suspect had been arrested.

A police spokesperson said the male suspect was the subject of the siege between East 14th and 15th avenues between High and Mill streets, but she would not immediately say where the boy was arrested or provide other details.

Police called SWAT and crisis negotiation teams to the scene and deployed a BearCat armored vehicle on Mill Alley.

From his position behind a shielded hatch atop the BearCat, an officer had kept a rifle trained on a home along the alley. Police used a loudspeaker aboard the armored vehicle to order the home's occupant to exit with their hands up.

Two drones also were operating in the area, including one that bobbed up and down outside a second story window of the Mill Alley residence.

At 8:45 p.m., Eugene police spokesperson Melinda McLaughlin issued a news release confirming the presence of SWAT and crisis negotiators.

"Due to the nature of the response SWAT and crisis negotiation teams were called out to more safely make contact," McLaughlin said. She added that a reverse 911 call had been sent out to nearby residences.

Police asked the public to avoid the area and urged residents in the area to stay indoors. Some residents were prevented from returning home, and a pizza delivery driver was turned away.

However, dozens of spectators gathered to observe the police activity.

Shortly before 8 p.m., a flash-bang device went off. Minutes later, police resumed hailing the home's occupants. About a half-hour later, an officer using the loudspeaker warned that they would send in a K9 and use gas.

The law enforcement activity prompted a UO alert shortly before 6 p.m.

The shooting Tuesday morning near Monroe Middle School left one person wounded. A bystander found the wounded person on the ground and helped police provide aid until medics arrived and took the victim to Sacred Heart Medical Center at RiverBend in Springfield for treatment.
