ORANGE CITY, Fla. (AP) — A conversation with two passengers landed a Florida tow truck driver in jail after his cellphone pocket-dialed 911 and dispatchers listened in.

Authorities say 19-year-old Matthew Dollarhide of Orange City was surprised when a Volusia County Sheriff’s deputy pulled him over on Tuesday and asked why they had been talking about selling drugs.

The Daytona Beach News-Journal reports deputies were alerted at 9:42 p.m. Tuesday and sent to a location where dispatchers said the phone signal was coming from. From the conversation, dispatchers learned that they were driving a tow truck and heard the name Harry. Deputies pulled over a Harry’s Towing truck moments later.

Authorities said deputies found a crack pipe on Dollarhide, who was arrested and charged with possession of drug paraphernalia.
