Bangalore: The city police have recovered twenty more empty cartridges taking to 32 the total number detected so far in the terror attack on the Indian Institute of Science campus here.

The recovery was made by the team of Forensic Science Laboratory (FSL) during their search at the J N Tata auditorium complex in the campus, Bangalore Police Commissioner Ajay Kumar Singh told reporters.

"The first comparison of the cartridges have suggested that all the rounds of ammunition have been fired from one weapon", he said disputing speculations that more than one weapon has been used in the attack.

Singh refuted reports that have appeared in a section of the press that his office has received a fax or letter threatening that bombs would explode at the Chief Minister N Dharam Singh's residence and also in a five star hotel.

It was a fact that the threatening letter received by media offices was secured by him and on the basis of it, bomb detection team and sniffer dogs were pressed into service at the Chief Minister's residence and Hotel Grand Ashoka, where nothing was found, he said.

In the wake of the terror attack, the city police have been contemplating to set up a separate intelligence wing for the city as had been done in some metros and the issue would be taken up with higher ups, Singh said.
