ST. AUGUSTINE, Florida (AP) -- Police have arrested a motorist they say had a 24-pack of beer strapped in with a seat belt but had a 16-month-old girl unrestrained in the back seat with the toddler's mother.

Tina D. Williams was pulled over in St. Augustine on Sunday for allegedly running a red light.

A 24-pack of Busch beer was strapped in with the passenger-side seat belt, according to an arrest report. The girl was in the back seat with 20-year-old Amber Tedrick, who is the toddler's mother.

Williams, 46, said she didn't know why the child wasn't restrained.

Williams refused to take a breath test and a deputy found two metal pipes commonly used to smoke drugs in her purse, authorities said. 

Williams was charged with driving under the influence, child abuse, possession of drug paraphernalia and driving without a license, a jail official said. She remained in the St. Johns County jail Tuesday after bail was set at $31,000.

The jail did not have the name of her attorney. It was not clear if Tedrick would face any charges, but the child was released to her care, according to The Florida Times-Union.
