Supt Neil Bhole, said: "This incident has caused significant disruption this morning but we have to put the safety of the public ahead of inconvenience and disruption and we make no apology for the steps taken.
"We have dealt with this as quickly as possible without jeopardising public safety and everything should now be returning to normal.
"We obviously cannot speculate on the motive for the bag being left where it was but will now be carrying out an investigation to try and trace the individual involved."
Metrolink and bus services going into the centre have now resumed normal service.
