Good thing they got them.

Four people suspected of planning an imminent attack in central Paris have been arrested by French police, according to reports.

The three men and a woman were already known to authorities as being suspected radical Islamists, reported TF1.

It was claimed two were French brothers of Turkish origin and authorities believed the group posed an imminent danger.

During a search this morning, investigators found a cartridge for an assault rifle, electronic material, USB sticks and a safe.

France is already on heightened alert following last November’s terror attacks in which 130 people were killed.
