ST. JOHN'S, N.L. -- Police in Newfoundland say a total of five suspicious packages have been reviewed without incident after courts and other buildings were cleared as a precaution on Wednesday.

RCMP Staff Sgt. Boyd Merrill says in a statement that the packages were in Grand Falls-Windsor, Gander, Stephenville, Clarenville and Grand Bank.

He says there are no known risks to public safety.

The rash of suspicious parcels prompted the Department of Transportation and Works to suspend operations at seven provincial mailrooms.

Some packages were intercepted before delivery.

Two more forced the evacuation of the provincial Supreme Court building in St. John's and the Danny Williams Building, a court complex in Corner Brook.

Three have been confirmed as originating from the same international address and with similar contents to packages reviewed by the RCMP in Nova Scotia.

But RCMP say they can't confirm any link with similar deliveries in Nova Scotia and Manitoba.

Cape Breton Regional Police were also investigating a suspicious package at the Justice Centre in Sydney, N.S., on Wednesday. Police said it appears to be similar in nature to those received elsewhere in the country.

They say the envelope was contained in a secure area and no one came into contact with its contents, but the main floor of the building was evacuated as a precaution.
