CBC news has learned that several businesses in the Avalon Mall in St. John's were shut down on Thursday as authorities arrested several people in connection with an immigration investigation. 

A witness at the mall described officers arresting workers at three, possibly more, kiosks at the mall around mid-morning on Thursday. 

CBC news has been told that one business sold hair straighteners, another offered massages, and a third kiosk sold toy helicopters.

In a written statement, the Canadian Border Services Agency said search warrants were executed in relation to an ongoing immigration file.

The agency described the file as a co-ordinated effort between officials in Newfoundland and Labrador, Nova Scotia, and New Brunswick. 

The statement said nothing about arrests. 

A relative of the owner of the kiosks said the incident involved a paperwork issue with the employees and that the issue will be straightened out.

Some of the businesses had re-opened by Thursday afternoon.
