Centre has said that punishing Kasab has given a clear cut message to the terrorist organisations in the country. Talking to reporters on the sidelines of Golden Jubilee Celebrations of Border Road Organisation in New Delhi today, the Defence Minister A K Antony said that the present law is sufficient to punish criminals and culprits like Kasab. Replying to a query on the alleged involvement of an army major in cyber security, the Defence Minister said that the investigation is on. The officer was interrogated by the Defence Ministry and officers from various other ministries. This is a clear cut case of cyber security breach but espionage has not been proved.
