(WEN) - Get Report

chili caper is over.

Anna Ayala, 39, was arrested Thursday night at her home in Las Vegas on charges of grand theft and attempted grand theft.

Ayala caused a stir last month when she claimed she bit down on a finger in a bowl of chili at a Wendy's restaurant in San Jose, Calif. Dublin, Ohio-based Wendy's said the claims hurt its sales in the area and moved to investigate.

The company subsequently offered a $50,000 reward for information in the case when tests of workers in its supply chain turned up no evidence of recent hand injuries. Wendy's doubled the reward last Friday.

The Associated Press

reported that the grand theft charge was not connected to the Wendy's case and was related to a 2002 incident in which Ayala allegedly tried to sell a mobile home in San Jose that she didn't own.

Ayala's credibility took a hit last week after it was reported that she was no longer represented by her original lawyer, was planning to drop her claim and had a history of suing big companies.

A Wendy's spokeswoman didn't immediately return a call Friday afternoon about whether anyone would collect the award.

"We're thrilled that an arrest has been made," Wendy's exec Tom Mueller said in a statement.

Wendy's rose 79 cents Friday to $41.54.
