So the word on the grapevine is that it's one sea lion but multiple attacks. Now rumor has it that the swimmers that got bit were triathletes who refused to take some downtime for the season. Ha! Joking aside, tri-club member Malik posted a warning on the club list, the gist of it is; 6 people attacked so far, no swimming at Aquatic Park until further notice.
It's a good thing it's the end of the year with a lot less people swimming.
