Orange County Sheriff Sandra Hutchens says five people were arrested in connection with the jail break last Friday but the three inmates are still at large.
Investigators believe the trio had "outside help" to facilitate the escape. No names were released. Hutchens also explained that more arrests are likely over the next 48 hours.
"Some of them knew these individuals, some of them are either on probation or have warrants," she said. Meanwhile the search continues for Jonathan Tieu, 20, Bac Duong, 43, and Hossein Nayeri, 37 who had all been awaiting trial for unrelated violent crimes.
