A Tuscaloosa woman was arrested Saturday after police said she lied about her ex-boyfriend raping her, and then tying her up.

Tuscaloosa police were dispatched at 5 p.m. to a home in the 1500 block of Greystone Drive on a report of a sexual assault. The alleged victim - 25-year-old Mariah Jordan Smith - told investigators her former boyfriend had entered her home through an unlocked door, went into her bedroom and sexually assaulted her, said Tuscaloosa County Metro Homicide Unit Capt. Gary Hood.

She told police that after the attack, he tied her legs to the bed, tied her hands together and left the home. While investigators interviewed Smith, they determined some of the statements she gave them were false, Hood said.

They then got in touch with the ex-boyfriend and he learned he was out of state during the entire time of the alleged sexual assault. Hood said investigators corroborated his alibi with local law enforcement there.

Investigators arrested Smith for filing a false report. She was booked into the Tuscaloosa County Jail with a $6,000.00 bond.
