State police divers are searching for the body of a man who went missing in Lake Hopatcong while celebrating his birthday.

Avinash Kuna and his friends were celebrating his birthday on a pontoon boat Saturday. His friends say that they jumped into the water to go swimming and Kuna screamed that something was pulling him down. They say that they could not get to him before he went under the water.

Friends are trying to raise money to eventually send Kuna’s body back to his family in India. A GoFundMe page had raised $25,000 as of Monday afternoon.
