(CNN) -- Canadian police say they're looking for possible connections between the discovery of severed body parts in two cities, including what appears to be a human foot mailed to the headquarters of the ruling Conservative Party.
The grisly find in an office tower in Ottawa on Tuesday came the same day that a janitor found human remains -- but not a full human body -- behind an apartment building in Montreal, about 200 km (160 miles) away.
Police also confirmed late Tuesday the discovery of a second human body part in Ottawa. No other details were immediately available.
"It would be foolish for us to disregard what is going on in Montreal," Constable Marc Soucy, an Ottawa police spokesman, told CNN. But both Soucy and Constable Daniel Fortier, his counterpart in Montreal, said there was no known connection between the incidents Tuesday night.
Soucy said a hazardous materials team was sent to the office tower that houses the Conservative offices in Ottawa shortly after 11 a.m. after workers reported a suspicious package. The officers who responded noticed what appeared to be bloodstains on the box, he said.
Ottawa police Sgt. Steve Hodgson told reporters outside the office that the package had been addressed to the Conservative Party. Staffers had begun to open the package before calling police, he said.
The party, led by Prime Minister Stephen Harper, had no comment on the incident Tuesday evening.
This is a prelude of things to come under Harper and the conservatives, when they are done with this country. Losing an appendage from the body would not be uncommon
Canadian murder suspect Luka Rocco Magnotta was arrested Monday in the German capital Berlin, the Bild newspaper reported.
The porn actor and stripper, who was the subject of a global manhunt after he allegedly murdered his gay Chinese lover and mailed body parts, was picked up at an internet cafe in Berlin's Neukolln district, the newspaper reported, citing police sources.
Magnotta, 29, fled Canada after the killing, initially heading to Paris.
Magnotta is wanted for threatening the Canadian prime minister, first-degree murder, defiling a corpse and using the mail system for delivering "obscene, indecent, immoral or scurrilous" material.
Kankan Huang, the owner of a Montreal convenience store where Jun Lin worked about 10 hours a week, said the victim was a responsible, polite cashier. He said he knew something was amiss when he didn't show up for work last week because Lin had never missed a shift since he was hired last August.
