New Delhi: Prosecution in Parliament attack case on July 15 got a boost when a ballistic expert told a Delhi court that the sample of firearms examined by him pertaining to the December 13 attack was the same as used by five Pakistani terrorists who were killed in the gun battle with the security forces.

"In my opinion, all the cartridges were linked with firearms sent to me and were fired from them. Most of the bullet pieces were linked with firearms," senior scientific officer, Central Forensic Science Laboratory (CFSL), A Dey said in the court of designated Judge S N Dhingra.

Deposing as a prosecution witness, the ballistic expert said all the fire arms sent to him were in working condition and the white crystalline material recovered from the houses of the arrested accused, Shaukat Hussain and Afzal was ammonium nitrate.

Another CFSL expert, T R Nehra, who compared the handwritings of Jaish-e-Mohammed militant Mohd Afzal from the seized documents, said the accused's signature tallied with the sample sent to him by the investigating agency.

"I did not observe any material divergence in the two handwritings," he told the court during his cross-examination.

The expert had compared Afzal's signature, which was found on the papers pertaining to the purchase of Ambassador car by the Pakistani militant Mohammed alias Leader, with which the five militants had stormed Parliament complex.

Afzal had signed the documents as attesting witness.

Meanwhile, CRPF cContstable Mahipal Singh, who was on duty with three of his companions in the Parliament House on December 13, said he saw the terrorists coming from the side of gate number 6 and one of them threw grenade on them.

"I saw terrorists firing on us. One of the terrorists threw hand grenade on us. It exploded near us and I received injuries on my legs and my three companions also received injuries," he said.

Two other witnesses, R S Verma, Director CFSL and Jasvinder Singh, Proprietor of a computer institute recorded their statements as prosecution witness.

Verma said he examined the explosives recovered from the car of the terrorists.

Singh said that the I-cards recovered from the possession of the slain terrorists were not issued by his institute and were fake.

"None of the persons whose photographs are on these I-cards had been students at our centre. The I-card, which is issued by our principal has different logo and design and is not similar to the I-card shown to me," he said.

The court is holding day-to-day hearing in the case and has till now examined 25 witnesses.

The accused have been charged with threatening the unity, integrity, security and sovereignty of the country by waging war against it and committing several other offences under POTA, IPC, Explosive Substance Act and Arms Act.
