(CNN) A delivery driver dropped off a parcel and made off with a dog, a British court heard Tuesday.

Levi Pislea, 22, who worked for an independent delivery service, was convicted of stealing Wilma, a miniature schnauzer, as he delivered an Amazon parcel in April last year.

According to Court News UK, Richard Guttfield, Wilma's owner, discovered the 11-month-old dog was missing from his home in Marsworth, southeast England, on April 27. After determining that Wilma vanished around the same time as his Amazon parcel arrived, he contacted the online retailer.

Pislea's manager questioned him about the dog, but the driver denied seeing Wilma, or entering the garden where she was kept. An app, however, revealed the truth: It traced his steps around Guttfield's house and into the garden.

Pislea's manager reported him to the police after going to his home and finding Wilma there.
