Emerging from the PMO, Bassi said investigators, probing the alleged raising of anti-India slogans at the JNU event, were looking at all aspects of the case including the motive.
"We have adequate evidence against him (Kumar). I won't be telling you about the process of investigation and what all we have found out so far," Bassi told reporters.
"People in huge numbers participated in it (the event), and we have already identified the ring leader. Now we are looking for all those who have been identified. Very soon we will get hold of them," he said.
Kumar was arrested on February 12 in connection with a case of sedition registered over holding of the event at the varsity last week to protest the hanging of Parliament attack convict Afzal Guru.
The Police Commissioner said he had come to the PMO to invite some officials for the At Home programme being hosted by him.
"Not at all," he said when asked whether there was any clean chit to Kumar. The JNU students and teachers are on a strike demanding Kumar's unconditional release.
Bassi said the the investigators have found that people from outside JNU also participated in the event.
"What we have found out is that people from outside besides those from JNU participated in the demonstration. Now what was the motive behind this is something we will look into. We are investigating all aspects in detail," he said.
"The situation at present reminds me of the verse 'Dekh tere sansar ki halaat kya ho gayi hain bhagwan, kitna badal gaya insaan' (Oh Lord what has this world come to, how much has the man changed)," he said.
