A 12-year-old boy who has not yet been identified has been taken into police custody. German authorities say he attempted to blow up a market in Ludwigshafen town.
In two separate incidemts, police say he left explosives in a rucksack in November which failed to detonate. A few days later, he planted an explosive device near a town hall.
A concerned individual alerted the police just in time and a tragedy was averted.
It is unclear if the boy has links to the Islamic State terror group and although he remains in police custody, he will not be charged to court. Under German law, he is under the age of criminal accountability.
