California college wrestler missing after being pulled into ocean during 'polar plunge'

A San Francisco State University student remains missing after he went in the ocean as part of a "polar plunge" and was pulled away Thursday.

SF State senior Hamzah Alsaudi went into the ocean near Pacifica, California, on Thursday, Jan. 19, the university said in a message to the community.

Authorities called off their search for Alsaudi on Friday, the statement said.

"Our thoughts and prayers are with the entire Gator community right now as we process this news," said university vice president Jamillah Moore, who added Alsaudi is a "beloved" member of the university wrestling team.

Friends said Alsaudi had gone to the beach with two teammates for a "polar plunge," KTVU reported.

What is a polar plunge?

A polar plunge usually consists of people swimming in a body of water during the winter, braving the cold temperature.

The events are popular with young people, can be organized community events and can include a fundraising aspect. In the case of the group Alsaudi was with, it was just three people and not an organized community event.
