A good Samaritan is credited with helping to save four people tossed into the water when their boat capsized under the Coronado Bridge Saturday.
The U.S. Coast Guard says the small boat overturned around 2:50 p.m., dumping the four on board.
A person in the area spotted the people in distress and began the rescue effort.
Harbor Police and Coast Guard crews soon arrived to help pull people out of the water. All victims were brought to San Diego to be checked out, but no one was injured.
Harbor Police was tasked with towing the abandoned vessel out of the waterway.
Investigators are still looking into the cause of the capsize.
