Police authorities have released a new surveillance video footage of missing Brown University student, Sunil Tripathi, captured around Brook Street at 1:33 a.m. on March 16, which is about 20 minutes after he last used his computer.

According to the police, the video footage images match the description of 22-year-old Tripathi. It shows a tall, skinny man wearing a black cap, dark jacket and jeans walking south on the Brook Street, which is not far from the students' home.

Investigators hope that this video will provide them clues to find the Ivy League student.

"This footage provides important clues that can help hone our search for Sunil," Tripathi's sister, Sangeeta Tripathi, told New York Daily News.

Sangeeta and her other brother Ravi Tripathi are also accessing several other surveillance videos for any signs of their lost brother. She denies any foul play in this incident.

The Federal Bureau of Investigation and the Providence police have joined hands to trace Tripathi, who has been missing for over two weeks.

During their investigation they also found a vague note in the student's apartment, but chose not to reveal the contents of the letter.

Tripathi, was reported missing from his Providence apartment, March 16. He was last seen in the campus at 11:00 a.m., wearing a black Eastern Mountain Sports ski jacket, blue jeans, a Philadelphia Eagles wool hat and thin black-rimmed glasses.

Tripathi, a philosophy major, was on an approved leave vacation from the university. He left his apartment alone without carrying his ID and credit cards, wallet or cell phone.

Tripathi's family revealed a face book page, "Help Us Find Sunil Tripathi" that he had struggled with depression.
