(NBC NEWS) -- Police surrounded a home Tuesday in Tacoma, Wash., where a man with at least four high-powered weapons was holed up after reportedly walking through the neighborhood spraying gunfire, a sheriff's official told NBC News.
No injuries were immediately reported, but Pierce County sheriff's Detective Ed Troyer said several homes were hit by bullets in the neighborhood in Tacoma, about 30 miles of Seattle.
It wasn't known whether anybody else was in the home with the gunman, who Troyer said was known to have "mental health issues" and was believed to have been drinking.
Police began firing tear gas into the house early Tuesday evening, NBC station KING of Seattle reported.
KING reported that numerous residents of the neighborhood had been evacuated and that those who remained were asked to stay inside.
Troyer told KING that the man, who he said was 67 years old and also had substance abuse issues, crashed his car last week in a DUI accident.
