The grenades found on the militants killed in yesterday’s pre-dawn encounter were of the same make as those used in the attack on Parliament, Police Commissioner S P S Yadav said.

He said the grenades bore the mark of manufacturer Arges, an Austrian company which has licensee units in Pakistan and some other countries.

“The same grenades were used by Lashkar-e-Toiba in the Parliament attack in 2001,” Yadav said, pointing to a Lashkar-e-Toiba link in Thursday’s attack on the RSS headquarters.

About the jottings in the diary recovered from the vehicle, he said none of the phone numbers was from India. The diary also had a map of Nagpur, he added.

Though Yadav was tight-lipped, sources said the militants killed in the encounter had been identified as Afzal Ahmed Butt and Bilal Ahmed Butta from Lahore, and Mohammed Usman Habib from Gujranwala.

Yadav said the car was 20 years old and its number plates bore a number that turned out to be of a two-wheeler in Aurangabad. Another number plate recovered from the car bore a Mumbai number.

‘‘We are still looking for the last genuine owner of the vehicle,’’ Yadav said.

He, however, didn’t confirm whether the attackers had a local link. ‘‘We are keeping a watch for their possible local sources,” he said, adding that the terrorists couldn’t have been carrying the explosives all the way from Patna.

“It must have been delivered to them in the city or at a place in the close vicinity,” he said.
