A California couple was arrested after getting caught having sex in the back seat of a parked car on a busy San Bernardino County street - but officials say that was only the beginning of an incident that left a sheriff's deputy in need of stitches.

Grand Terrace residents, including a middle school student, reported seeing a couple having sex in the 22000 block of Newport Avenue about 3:45 p.m. Thursday, when children were walking home from school, according to the San Bernardino County Sheriff's Department.

A responding deputy found a couple in their 20s in the back seat. He asked them to get dressed, and when they got out of the car he handcuffed them.

The woman, identified as 23-year-old Cristi Caraveo, allegedly slipped the handcuffs from behind to in front of her, jumped in the car and accelerated toward the deputy, sheriff's officials said.

The deputy suffered a cut to his left hand that required several stitches.

Caraveo was later found at her home about 10 miles away in Bloomington and taken into custody without incident.

She faces charges of assault on a police officer with a weapon, escape and indecent exposure, sheriff's officials said. She was in jail on a no-bail hold.

Caraveo's mother said her daughter had moved back home recently and was unaware of what her daughter was accused of.

The man she was with, identified as 24-year-old Emanuel Olivares of Grand Terrace, faces charges of indecent exposure and obstructing an officer, sheriff's officials said. As of Friday, he was not in custody.
