(UPI) A woman who stopped into a Florida CVS store to buy a birthday card a few minutes before closing time said she ended up locked alone inside the store.

Lillian Rimmel of Orlando said she was visiting a friend in Titusville when she stopped into the town's CVS to buy a birthday card about 9:50 p.m. Friday.

Rimmel, who said she was unaware that the store closed at 10 p.m., said she took her card up front just after 10 and discovered she was alone in the store.

"I'm walking back to pay for it, and all the alarms started going off," Rimmel told WESH-TV.

She said the motion sensor alarm was blaring a siren as she searched for a way out of the shop, which was locked down with a metal security gate over the front entrance.

"I started screaming, 'Is anyone here? Can anyone help me?'" Rimmel recalled to Florida Today.

Rimmel called a friend who advised her to dial 911.

"All I could hear were alarms," the friend, Jacqueline Burt, said of the phone call. I told her to call 911 because I didn't want them to go in there with guns.

Rimmel said she made sure she was in view of a security camera as she dialed 911, so it would be clear that she was not up to anything illegal.

"I was shaking. I was scared, but I wasn't scared for my life. I was just so nervous that I did something wrong," she said. I didn't know how this could happen. I was dumbfounded, she said.
