Officials continued to search for a missing swimmer on Monday, Dec. 22, following a reported shark sighting over the weekend in Northern California that closed beaches.

About noon on Sunday, Dec. 21, the Pacific Grove Police Department and Monterey Fire Department responded to a report of a missing swimmer off Lovers Point, according to a joint Statement from the City of Pacific Grove, City of Monterey and U.S. Coast Guard.

"Two witnesses indicated the swimmer may have encountered a shark while swimming offshore near Lovers Point," the release reads.

Lovers Point is in Pacific Grove, a coastal city near Monterey about 115 miles south of San Francisco.

Emergency response teams then began conducting a search and rescue mission with support from the United States Coast Guard, Monterey County Sheriff’s Office, and California State Parks, but by 8 p.m. local time, the swimmer was still not sighted.
