A Montreal man has been arrested after police were tipped that death threats were made on Facebook.
Quebec provincial police say David Abitbol was arrested at his parents' home on Saturday.
Police say they found five weapons and hundreds of rounds of ammunition.
Police spokesman Richard Gagné says Abitbol, 28, has been charged with uttering death threats and with firearms violations after some of his former college acquaintances were threatened.
The arrest came a day after police received a tip that someone using the moniker "Dark Killer" had written threatening messages on Facebook.
Abitbol was arraigned on Saturday and will remain in custody until he returns to court on Monday.
