Police dispatchers are no strangers to accidental calls, although usually these “butt dials” reveal little more than muffled, innocuous chatter, broadcast from the pocket of an innocent civilian. But when a 24-year-old Pennsylvania man accidentally called the police from his pocket Wednesday, the operator overheard and recorded the entire conversation. One he was having with his drug dealer.

Justin Kryzanowski now faces charges of possession of a controlled substance, possession of drug paraphernalia and prohibited offensive weapons, the Scranton Times-Tribune reports. After listening as the drug deal went down, police traced Kryzanowski’s cell phone back to his residence in Scranton, Penn., where they found various prescription medications, drug paraphernalia, brass knuckles and syringes loaded with Suboxone, a medication used to treat opioid addiction.

Police also found the cellphone that matched the number that had called 911. Kryzanowski told police he’d been in a car with a man named Rick, according to the criminal complaint. Rick gave him the Suboxone, which he took shortly thereafter, he said.

Information on Kryzanowski’s arraignment, preliminary hearing and bail is not yet available. In the meantime, let Kryzanowski’s fate be a reminder: if you’re planning on breaking the law, please doublecheck that you’ve locked your phone.
