Llyas Choudry is with the Islamic Outreach Center in Cypress and says pigs are sometimes used as symbols against Muslims.
"There are certain religious regulations in terms of dietary things. It is not kosher meat, the meat of pig. So people sometimes they use it as a symbol, maybe symbolically."
Authorities are investigating the incident. Choudry says the mosque opened in August and so far has been welcomed by neighbors in the area.
