Thiruvananthapuram: Security has been tightened at ISRO centres across the country after the recent attack on Indian Institute of Science, Bangalore, ISRO chairman G Madhavan Nair said today (Jan 2, 2006).

"Our system is already tight. The Central Industrial Security Force (CISF) is looking after the security and we have asked them to be extra-vigilant," Nair told reporters here.

Nair said the attack on scientists at IISc was most unfortunate.
