A 26-year-old man was shot Wednesday in NE Portland and his mother has been detained for questioning, police say.

Portland officers responded a little before 8:30 p.m. to the 10500 block of Northeast Davis Street after someone reported gunfire coming from the yard of a home, police said.

The 53-year-old mother told officers she was involved in an altercation with her adult son, police said. Investigators determined there was at least one shot fired during the encounter and the son left soon after, according to police.

The son arrived at a Portland hospital sometime after with a gunshot wound. Police said he is expected to survive.

The specific circumstances of the shooting and the identities of the family members have not yet been released by police. No charges have been announced in the shooting.

Portland police ask anyone with information on this shooting to contact the agency's non-emergency line at 503-823-3333.
