A gunman walked through a neighborhood in Tacoma, Washington and fired at houses indiscriminately, according to multiple media reports.

No injuries have been reported.

Police contained the gunman within his home. He has refused to surrender and is believed to have multiple firearms.

Sheriff's spokesman Ed Troyer said the man has mental health issues. He may have been drinking before the incident.

Media helicopters have been ordered to stay 3 miles away.

"His firepower is strong enough to reach the helicopters," Troyer said.
