The U.S. Marshals Service has lost track of over 2,000 encrypted two-way radios and other devices worth millions of dollars, the Wall Street Journal reported on Sunday.

According to internal agency documents obtained by the Journal, the problem was brought to the attention of officials in 2011 by the service’s Office of Strategic Technology.

Those looking into the unaccounted-for equipment estimate that the value of missing radios is at least $6 million – each radio costs a few thousand dollars. They suspect that employees often failed to report lost devices because it would require additional paperwork and could have lead to an internal investigation.

Though no incidents jeopardizing the public safety or the safety of those individuals under the agency’s protection have been reported, some marshals are concerned that criminals could get their hands on the missing radios and use them to monitor law-enforcement activities, according to Fox News.

A report by the technology office stated that “negligence and incompetence has resulted in a grievous mismanagement of millions of dollars of USMS property” and that “the entire system is broken and drastic measures need to be taken” in order to prevent such tools from being misplaced. The Marshals Service is planning to implement a new inventory-tracking system, a spokesman told the Journal.
