The girls, aged 16 and 17, had attended the classes on the day and had left the college at around 2.30 pm, the college authorities said.
They had also produced before the police the CCTV images of the girls leaving the college at that time. The parents of the commerce students registered a missing complaint with police on the evening of Feb 1 itself.
Police said they were finding it difficult to locate the students as they were not carrying mobile phones with them. The girls also did not have much money with them, they said.
However, no substantial clue was available, police said. Photos of the girls have been published in the social media seeking the co-operation of the public in the search.
