An off-duty Bexar County deputy was assaulted early Saturday morning while working security at a northwest side restaurant.
The deputy worked security at Ojos Locos Cantina on Loop 410 at Exchange Parkway around 2 a.m.
Police say a group of two women and two men got rowdy inside the business, and the deputy was escorting them from the restaurant when they attacked.
Another deputy working security rushed to help.
Police say they managed to subdue and arrest all four and say they will be charged with assault on a peace officer and resisting arrest.
Officers say three of the suspects also had outstanding warrants.
