The incident is affecting bus and Metrolink services. Flights have not been delayed by the ongoing incident. Travellers in the area said there were police and dog units seen in the area. Stagecoach said bus services will be terminating at Radisson Blue, due to an area around the bus station being closed.

Metrolink services on the Manchester Airport line can only travel from Victoria to Wythenshawe town centre. Passengers are able to use their tickets on bus routes.

In a statement Metrolink said: “Due to a police incident at Manchester Airport, services on the Manchester Airport line will only operate from Victoria – Wythenshawe town centre.” There are reports on social media that one man has been detained. There are pictures of a naked man running around the area and a controlled explosion has been carried out.

This comes on a bad day for the UK Travel industry as Thomas Cook, the world’s oldest travel firm, collapsed on Monday, stranding hundreds of thousands of holidaymakers around the globe and sparking the largest peacetime repatriation effort in British history.

The firm runs hotels, resorts and airlines for 19 million people a year in 16 countries. It currently has 600,000 people abroad, forcing governments and insurance companies to coordinate a huge rescue operation.
