U.K. Home Secretary Amber Rudd called leaks to the U.S. press about the investigation into Monday's terrorist attack in Manchester "irritating," and warned that it "should never happen again," reports CNN. Many of the details that were disclosed following the initial reports of the blast, which left 22 dead and many more injured, were traced back to U.S. law enforcement sources.
The UK Police Chiefs Council also released a statement reading in part:
"We greatly value the important relationships we have with our... partners around the world.... When that trust is breached it undermines these relationships, and undermines our investigations."
