It appears that some packages containing a suspect white powder where opened in the morning post today at Leeds Civic Hall on Calverley Street.
Staff who came into contact with the substance have been quarantined as a precaution. Police have been on site for a number of hours and are deferring further comment at this time.
Evacuation is a possibility after further tests have been carried out.
