More than 70 law enforcement personnel were at a Hyatt Hotel in Thousand Oaks investigating reports of shots fired early Thursday morning.
Ventura County sheriff's deputies responded around 2:30 a.m. to reports of a shooting inside the Hyatt Westlake Plaza in the 800 block of South Westlake Boulevard, officials said.
Sheriff's Capt. Don Aguilar said there have been no reports of injuries and no arrests have been made.
The hotel has not been locked down, but authorities set up a perimeter around the area limiting access. Hotel guests, however, are free to leave, he added, and no roads have been closed.
"There appeared to be some information that a shooting occurred here, but we're still trying to confirm," Aguilar said. "We're continuing to investigate."
A hotel employee reached Thursday said no manager or spokesperson was available to comment.
