**Updated** Halifax police charge six people after protest at Canada Post facility
**Updated at 11:10 a.m.**
Halifax police say six people arrested Sunday night outside a Canada Post sorting facility in the city's north end have been charged with mischief and obstructing a peace officer.
Police say protesters were posing a "serious public safety threat" and not complying with officers' attempts to disperse them.
They say they responded to reports that several vehicles were clogging up traffic on a street near the facility, "impacting two-way traffic."
The force says it "respects and upholds the right of citizens for peaceful and safe protest," but officers acted in the interest of public safety.
Police say the six people who have been charged are scheduled to appear Monday in Halifax provincial court.
Protesters have been rallying outside Canada Post facilities throughout the weekend, after the federal government legislated postal workers back on the job.
In a statement Saturday afternoon, Canada Post said it had contacted police about a similar rally in Mississauga, Ont., and was considering its options to deal with the demonstrations.
