‘Jihad Jane’ is allegedly the mastermind behind the plot to murder Swedish cartoonist Lars Vilks. Colleen Renee LaRose, who dubbed herself “Jihad Jane” on her YouTube account, hosted terrorist propaganda on her website and encouraged a Jihad against Vilks.

LaRose has been in custody since her arrest in connection with the plot last October.

She spent two weeks in Ireland while on a fact finding mission to find willing "Martyrs" for the murder plot.

Unknown to LaRose was that the Irish police and CIA were keeping her under close surveillance.

During her visit she was in constant contact with a 49-year-old Algerian who was arrested by Irish police on Tuesday morning. The Algerian man is the prime suspect in the murder plot.

All of the terror suspects are legal residents in Ireland. They include a Palestinian, a Croat, a Libyan and two other Algerian, and some have been resident in Ireland for up to 10 years.

LaRose befriended the suspects on the Internet and then gave them passwords to secret online chatrooms.

Investigators say this is were the murder plot was discussed in detail.

The Irish police have spoken to 25 other people who personally know the suspects to ascertain whether they attempted to radicalize any other Irish residents.

The Irish police have also dismissed claims that the suspects are an Al-Qaida cell.

Last night authorities were granted permission to detain the suspects for a week of questioning without charge.

The police are currently examining Mobile phones and computers that were seized in the suspects’ property.

It is not known at this time if the suspects will be charged with terrorist offences.
