An 84-year-old man's date with two teen twins didn't go as planned when the girls tied him up and robbed him.

Paul Aronson met Shaina Foster, 17, through SeekingArrangement.com - a website that calls itself a place "where beautiful, successful people fuel mutually beneficial relationships."

Shaina brought her twin sister, Shalaine Foster, on the couple's second date to an "expensive restaurant" that ended with the two of them being brought back to Aronson's house, reported New York Times. 

The man was apparently being "creepy," which prompted the twins to fasten him to a coffee table with zip ties for nearly 20 hours. They stole $470 cash and credit cards from his wallet and went on a shopping spree, according to the NY Times. 

"He asked to do things I wasn't going to do," Shaina told Detective Darryl Ng. "He is ugly, old and disgusting. I tied him up. I took his money and left. He was starting to creep me out." 

Shalaine's lawyer told the NY Times that his client "got caught up in something not of her making." Shalaine supposedly was only a bystander while her twin committed the crime. 

"The old man reported me? I don't understand why he reported me. He asked to do things that I wasn't going to do," Shaina said in court. Her lawyer declined to comment on the case.
