No injuries following reports of shots fired at Highline College in Washington state

WASHINGTON STATE-  Fire officials in Washington state say they know of no people with injuries following reports of possible shots fired at a community college south of Seattle.

Police armed with heavy weaponry swarmed Highline College in the city of Des Moines Friday morning after the reports of shots. Students were told to shelter in place as police searched the campus.

About an hour after the initial report, the South King Fire agency tweeted it knew of "no known" victims.

Police say they are trying to determine whether shots were fired.

The school is located about 15 miles south of Seattle in Des Moines, Washington. It has about 17,000 students.

SWAT team officers carrying guns were seen on video walking around one of the school's parking lots.

"They're looking for and trying to confirm that shots were fired," Washington State Patrol trooper Rick Johnson had said earlier.

His agency was asked to shut down a portion of Interstate 5 near the campus while other agencies investigate the reports.

The lockdown comes two days after a mass shooting at a high school in Parkland, Florida, left 17 people dead.

Police in Renton, Washington, near the Highline campus, said they were among the agencies responding to the reports.

Highline College's Facebook page first mentioned a lockdown and the report of shots fired in a post shortly before 9 a.m. PT (noon ET).
