Authorities in Perth said Katrina Purll, 29, pleaded guilty Tuesday to possession of $23 worth of cocaine and was ordered to pay a $460 fine, The Daily Record, Glasgow, reported Wednesday.

"It seems not to have crossed her mind that the first thing we do with a bag which is handed in is have a good look through it," a police source told the Record. "There was a small bag of cocaine and no one expected the owner to ask for it back." John McLaughlin, Purll's lawyer, said his client discovered the bag of cocaine on a cistern. "The barman said she should take it to the police. She accepts going to collect it was a naive and foolish thing to do," McLaughlin said.
