A man’s body was found floating in the Pacific Ocean, just south of an oil island, in Long Beach Sunday afternoon, according to officials.

Authorities received a call just before 2 p.m. from a person on a small fishing boat who discovered the body in the water just south of Island Freeman—one of four oil islands operated by THUMS off the coast of Long Beach—according to Long Beach Fire Department spokesman Matt Dobberpuhl.

Officials responded about 20 minutes later and confirmed the man was wearing street clothes and appeared to have been in the water for quite a while and obviously deceased, Dobberpuhl said.

Long Beach police and coroner officials are now investigating the incident and will determine the cause of death and the victim’s identity.

No other information is available at this time.
