SUFFOLK, Va. (WVEC) -- FBI agents swarmed a residence at the Magnolia Lakes Mobile Home Park in Suffolk on Thursday morning.

It happened just off of Magnolia Lakes Drive, not far from Nansemond Parkway and Portsmouth Boulevard.

The FBI tells 13News Now their agents were at the mobile home park for "court-authorized law enforcement."

The case and documents are sealed, however.

Witnesses said they saw five to seven unmarked cars right next to the home law enforcement was visiting.

"The place was just surrounded by cars. It was very strange," said neighbor Will Cutchins. "There were a couple of low-flying planes to, I think, take pictures of the area... so it was just more crowded than usual."

Next-door neighbor Christianna Clark said she saw the FBI while she was dropping her kid off at the bust stop right, which was right next to the scene.

"It was just really unusual, because things like that don’t happen in this neighborhood. It’s really quiet out here," said Clark.

"I was really worried that something had happened to the people that live next-door," she said. "They (the neighbors) just seem like really nice people. The grandmother is really sweet, but very quiet."

We knocked on the door of the family who lives in the mobile home. They declined to comment.

No other information about the FBI operation was immediately available.
