The German police had received information about plans to carry out a bomb attack on a gurdwara in Essen by a group of teenagers from one of the suspects' mother some weeks before an explosive was detonated there, media reports have claimed.
A third suspect has been arrested in connection with the terror bombing of a gurdwara by suspected Islamist militants in Germany's western city of Essen.
The 16-year-old youth was also arrested for an attempted burglary at a shop in the city a day before the attack, a police spokesman said.
