First responders were searching for a man who reportedly jumped off a Catalina Express boat on its way from the island to the mainland Thursday evening, authorities say.

At 5:55 p.m. the Los Angeles County Fire Department received a call of a person overboard near the Los Angeles Harbor Lighthouse, approximately three miles off the Port of Long Beach.

Witnesses described seeing the man intentionally go into the water, according to authorities. “About three miles off the breakwater, he jumped off the boat,” said Brian Fisk, a spokesman for the Long Beach Fire Department.

According to Los Angeles County Fire Department Dispatch Supervisor Michael Pittman, a team of at least 70 members of several local agencies, including the Los Angeles County sheriff’s and fire departments, the Coast Guard and the Long Beach Fire Department, is currently searching for the man using boats and helicopters.

“About as many as we can have out there,” Pittman said.
