Witnesses have described the ordeal as “so scary” as shoppers were ordered to “leave immediately”.
The Ashton-under-Lyne Ikea store was placed in an apparent “lockdown”, with social media flooded with confused customers outside the Swedish furniture store on Wellington Road at roughly 7:15pm.
One witness said that the store remains closed and no one is allowed to enter the store, according to the Manchester Evening News.
People also reported hearing alarms blaring as they retreated to their vehicles in the car park.
John Junior, who witnessed the ordeal, tweeted: “We got evacuated from Ikea in Ashton Under Lyne. Just so scary.”
