After a third bomb in less than a week jolted the region around the Golden Temple in Amritsar, India’s police reported that five suspects had been detained on Thursday.

According to state police director general Gaurav Yadav, two of the accused provided the supplies while the other three worked on the IEDs in a guest home in the city.

The wife of one suspect is also being questioned by police. According to Yadav, police have confiscated their phones and electronic equipment.

He claimed there were still ongoing investigations but provided no information about their alleged motivations.

Yadav was cited by Indian media as claiming that the explosions on May 6, May 8, and just after midnight on May 10 happened outside the temple, which holds the sacred texts of Sikhism.

He said that in the first incident, one of the suspects dropped a bag-containing a handmade bomb with around 200 grammes of explosives from the top of a building before detonating it.

In the early morning hours, the second device was also set up in a comparable manner, he said. Police did not confirm the overall number of injuries or offer any other information on the third explosion.

But according to Indian media, the first bomb caused at least one injury while the second blast caused six.

Yadav said that police found the culprits and made arrests on Thursday using CCTV video from the third explosion.

According to Yadav, the five suspects “have confessed that they were behind all three explosions,” calling the arrests a “breakthrough.”
