French authorities have detained a 17-year-old on suspicion of plotting attacks against embassies or official buildings.

Axar.az reports, citing Al Arabiya, the teen was formally put under investigation and locked up on Friday.

He was arrested on Monday at his parents’ home where he lived in the western Sarthe region and suffered light injuries as he tried to escape police.

One of the sources said a search of the home found a pledge of allegiance to ISIS and a list of schools in Le Mans, Sarthe’s main city.

Alongside the list was written a quantity of liters, thought to possibly refer to ingredients for incendiary devices or chemical explosives.

The 17-year-old was also suspected of targeting the embassies of Israel, Britain and the United States and the French interior ministry and various media headquarters, all located in Paris, as well as the European parliament in Strasbourg.
