The Department for Transport has stopped UPS from screening air cargo at some UK facilities because of security concerns.
In a statement, UPS said: “A Department for Transport scheduled review identified areas of concern UPS is working to address. As a result, some facilities in the UK have been temporarily taken offline, which in some cases has led to delays in the movement of packages.”
The carrier said it had activated contingency plans and expected service levels to return to normal early next week.
The move follows an incident last October, involving a bomb alert on a UPS cargo aircraft at East Midlands airport. In another incident in March a fake bomb was found on a UPS plane.
The UPS statement said: “In cooperation with the Department for Transport, UPS continues to assess the operation of its UK network to ensure full compliance of EU and UK security requirements, leading to a higher level of service to its customers.”
