NIA arrests 3 in Himachal police station blast probe

Something very serious happened at a police station in a part of India called Himachal Pradesh.

A big explosion, called a blast, took place there.

A special team called the NIA, which handles very important and dangerous cases in India, is investigating what happened.

The NIA has now arrested three people whose names are Mahavir Kumar, Ajay Mehra, and Manpreet Singh.

The team says these three people were likely involved in making the blast happen.

But the NIA does not think it is finished yet.

They believe there may be a bigger plan, or a "larger conspiracy," behind the explosion.

So the investigators are looking for other people who may have helped.

The police want to make sure everyone who was part of this is found.

The investigation is still going on.
