DETROIT (AP) – Detroit police say the department’s communications system is working properly again after a technical issue disrupted radio operations.

The department says a tower malfunction caused the system’s main server to overheat, resulting in a shutdown about 2:20 a.m. Monday that lasted about two hours. During the shutdown, officers were dispatched to high-priority calls via their personal cellphones.

In a statement, police Chief James Craig says the department “will continue to work diligently to improve our technology to better assist us in responding to the needs of our citizens.”
