A 25-year-old Boston University student with bipolar disorder who was visiting the Big Apple has been missing for at least a week, his concerned family said.

Zac Camhi was last spotted leaving the East Side W Hotel on 49th Street — and his family is getting more concerned about his safety each day.

“It’s very tough for me to share this,” his older sister, Tiffany, wrote on Facebook urging her friends to share his photo in hopes of
tracking him down.

“He has no identification, wallet or phone on him.”

Camhi also doesn’t have the medication he “desperately needs for his mental health,” Tiffany wrote.

A missing person poster was shared on Reddit, leading to a tip that a distressed person matching Camhi’s description was seen in Bryant Park last Thursday.

“If you’re in that area please keep your eyes peeled,” Tiffany pleaded.

Camhi was last seen wearing a maroon button-up shirt and dark-colored pants.
