They said they were keen to find out what had happened.
Two police cars remained at the rear of the property near Cross Street and a patrol car was still parked at the front shortly before 11am.
Two people appeared to be seated in the back of the car on Albert Road.
Plain clothes officers, one wearing blue forensic gloves, had arrived and had entered the property, a healthy-food themed-takeaway.
The premises are in a busy central shopping district.
