Punjab Director General of Police (DGP) V K Bhawra after a meeting with senior officials told reporters that a projectile had hit the building and the explosive used in it seems to be TNT (trinitrotoluene).
The rocket-propelled grenade (RPG) was fired at the third floor of the highly-guarded building in Mohali’s Sector 77 on Monday night and the explosion shattered window panes. No one was injured in the incident.
Here is a look at what TNT and RPG are:
An explosive that was used even in the world wars, TNT is a yellow, odorless solid. It is made by combining toluene with a mixture of nitric and sulfuric acids. It is highly explosive and at the same time insensitive to shock and friction. These qualities make it a widely-used munition.

Attack on Israeli diplomat
One of the major terror attacks in the country where the use of TNT surfaced was a strike against an Israeli diplomat.
According to media reports, the Central Forensic Science Laboratory had identified trinitrotoluene (TNT) as the explosive material used in the strike. The 31-page forensic report was handed over to Delhi Police investigating the February 13, 2012 bombing of diplomat Tal Yehoshua Koren’s car.
There have been other instances of the suspected or actual use of TNT in terror attacks across the world.
According to reports, one of the deadliest attacks using TNT was carried in Manila, Philippines in 2004. A television set containing a TNT bomb was placed in a ship MV super ferry 14. The blast, reportedly carried out by Abu Sayyaf group, resulted in the deaths of the over hundred people.
In 2020, Turkish authorities had claimed to have seized several kilograms of the explosive that they claimed was meant to be used for subversive activity.
What is RPG 22
According to some newsreports, the explosive device was believed to have been fired at the Punjab Police building from a RPG 22 or a rocket propelled grenade.
The weapon is of Soviet make and now used by the security forces of several countries. It is believed that an RPG 22 can hurl a projectile around 200-300 meters. While some of these launchers of this kind can be reloaded others are single-use disposable weapons. RPG 22 is believed to be in the disposable category.
These anti-tank weapons were also used in Afghanistan.
In 2000, an attack on a building of the British spy agency MI6 was reportedly carried out through a RPG 22.
The weapons and others similar to it have also been used in the ongoing Russia-Ukraine conflict.
The police is still carrying out its investigations on the basis of initial evidence and even claims to have leads in the Mohali attack.
