Montreal police say foot found on street this morning by passerby

MONTREAL - The discovery of yet another human foot is being investigated by police.

In Montreal, the limb was spotted by a passerby this morning next to a sidewalk in the city's west end.

It's the third time in less than a week that a severed foot has been found somewhere in Canada.

It's unclear how many of the cases are related.

Luka Rocca Magnotta, a porn actor and male escort, has been arrested in Germany in connection with a slaying and dismemberment in Montreal.

It's unknown whether discoveries in Vancouver on Tuesday and this morning in Montreal are linked to the original body-parts case.

Magnotta was the suspect after a torso was found in a Montreal back alley and body parts were mailed to political parties in Ottawa.
