Delhi Police Commissioner B. S. Bassi on Monday said the five JNU students, who are facing sedition charges for allegedly raising anti - India slogans, should join the probe and prove that they are innocent.
"They (the students) should join the probe. If they are innocent, they should present evidence of their innocence, " Bassi told reporters.
The five students - - Umar Khalid, Anant Prakash Narayan, Ashutosh Kumar, Rama Naga and Anirban Bhattacharya - - returned to the Jawaharlal Nehru University (JNU) campus on Sunday night.
They had disappeared from the campus after the February 9 event held to mark the anniversaries of executions of parliament attack convict Afzal Guru and Jammu Kashmir Liberation Front co - founder Maqbool Bhat.
Asked if police would enter the campus to arrest the students, Bassi said: "I am confident that my team is competent enough to deal with the matter.
"The investigating officer would take the best available option. The world is full of opportunities and options, " he said.
"Police have proper evidence against the one who is arrested, and in future too arrests will be made only after proper probe, " Bassi added.
JNU has been on the boil over the arrest of its students' union president Kanhaiya Kumar on sedition charges following the February 9 event.
