The Dallas Museum of Art is opening later than usual on Sunday, following an undisclosed threat that was made against the facility.

The Museum, which usually opens at 11 am on Sundays, will open at 2 pm instead.

At 9:44 am, the Museum announced that the building and the garage would be closed until further notice, and advised patrons to avoid the area, with a tweet that said IMPORTANT MESSAGE.

"Please do not visit the DMA at this time, and check back here for updates," it said. "We apologize for any inconvenience and look forward to seeing you soon."

No details were given at that time, other than the fact that the Museum had received a threat "against the building and the garage."

By 12:27 pm, the Museum followed with an update that the Dallas Police Department had checked out the situation and given the all clear.

"Thank you for your understanding and patience," their post said. "Earlier this morning, we received notification of a threat against our facilities. We notified the Dallas Police Department and shut down operations until DPD could ensure the safety of our patrons, staff, and community. We are happy to report DPD has since issued an all-clear and we will be reopening to the public at 2 pm."

"As always, the safety of our guests and staff is our top priority," they continued. "While we hate to see threats like this occur, we are thankful for the brave men and women of DPD and DMA staff who stepped into action on behalf of our community. Our staff is now onsite and looks forward to welcoming you soon!"
