SAN DIEGO (NEWS 8) - Parents expressed their concerns Monday night after a man was arrested for allegedly groping at least two females at a South Bay water park. 

"We thought this was a family park, so we wouldn't think that kind of behavior would be going on around here," said one parent. 

Chula Vista Police took 25-year-old Sergio Santos into custody on Thursday at SeaWorld's Aquatica San Diego. 

According to police, Santos tried to run way and assaulted a security guard in the process. 

Anyone with information on this case is asked to call Crime Stoppers at 888-580-8477.
