The Baltimore Police Department has used an invasive and controversial cellphone tracking device thousands of times in recent years while following instructions from the FBI to withhold information about it from prosecutors and judges, a detective revealed in court testimony Wednesday.
The testimony shows for the first time how frequently city police are using a cell site simulator, more commonly known as a "stingray," a technology that authorities have gone to great lengths to avoid disclosing.
The device mimics a cellphone tower to force phones within its range to connect. Police use it to track down stolen phones or find people.
