A woman has been detained by police after attempting to burn down a Las Vegas LGBT centre during a movie night.

The incident occurred on Saturday night at The Gay & Lesbian Community Center of Southern Nevada.

21-year-old Grewndolyn Glancey was detained after attempting to set a fire in the lobby of the LGBT centre.

According to reports from the Review Journal and KTNV, security officers raised the alarm after spotting her on CCTV, apprehending her as she set books on fire.

Glancey faces a charge of first-degree arson.

According to local media, she insisted the LGBT community “need to pay for their sins.”

The woman also claimed that Oprah Winfrey had instructed her to set the fires, and was taken to Valley Hospital for care.

However, she was later discharged and transported to Clark County Detention Center on an arson charge.

Andre Wade, the Operations Director at The Center, told Las Vegas News: “It was someone we’ve dealt with before who had been 86’ed.

“It was in this area and she went off into the corner and you couldn’t see her for a while but you could see activity, and eventually when she left you could see smoke billowing out.

“It’s perhaps some mental health issues that may have gone unaddressed but it’s really a statement that the resources that we need in this community to make sure that people have the help that they need.”
