"If you see international or national situation, Goa is vulnerable to terror attack," Mohan told reporters after unveiling 'Little Police' scheme in the city.
The state police department has been getting inputs from intelligence agencies on a regular basis, he said.
"We go by what intelligence agencies guide us. There are foreign tourists coming here, who can be the target of terrorists. Goa is known tourism destination," the DGP said.
"We have taken precautions. We have Anti-Terror Squad and also India Reserve Battalion, which has been constantly on the guard on the beaches," the DGP added.
"It is expected that there is damage. Those who come are not worried about their lives. Collateral damage cannot be ruled out in any act of terror," he said.
