The MAX Blue Line resumed regular service shortly after 1:30 p.m. Friday following police investigation of a shooting reported on the East 172nd Avenue Station platform in Gresham.

Gresham police have detained a suspect who was captured south of the platform, which was reported at 11:52 a.m., said police spokeswoman Officer Malaa Kerbs. The suspect's name and age were not available Friday afternoon.

A man was brought to the hospital for treatment of a bullet that grazed his face, Kerbs said. Also, a bullet went through the clothing of a woman who was with the man, she said.

The man and woman told police they did not know their assailant who was on the same eastbound Blue Line MAX car, Kerbs said. The gunman left the car and followed the couple who also exited the car at the East 172nd Avenue Station stop, she said.

"They don't know who he is," Kerbs said. "One question was asked inside the MAX. When they got out there was no argument that preceded it."

Officers searching for the alleged shooter stopped a man matching the suspect's description south of the MAX platform, Krebs said. She said the suspect is at a hospital for treatment of a separated shoulder, adding that she did not know how the injury occurred.
