Police in Canada say they have arrested a suspected Islamic State fighter following last month’s arrests of three suspected ISIS recruiters in Ottawa.

Authorities say that today’s arrest is related to the terror cell they busted in January.

“[The case] involves alleged recruiting for the Islamic State group and Canadian John Maguire, a fighter who appeared in an IS video overseas and who reportedly might have been killed recently.

The official, who spoke on condition of anonymity ahead of the announcement Tuesday, says charges will be brought against Maguire, who police can't confirm is dead. The official says they will also announce charges against a third man.

Suliman Mohamed, 21, was charged last month with participating in a terrorist group.

According to authorities, the cell was focused on fighting with ISIS overseas, not conducting terror attacks at home.
