A mother of three was arrested this week on suspicion of texting while driving with an infant in her lap on the 405 Freeway, police said.

Shawndeeia Bowen, 29, was arrested Tuesday after another driver spotted her on the northbound 405, according to Lt. Steve D'Anjou of the Torrance Police Department.

"A citizen saw it and thought it was so dangerous that he called 911 on his cellphone and continued to follow her the whole way," D'Anjou said, according to KTLA-TV.

Torrance police pulled over Bowen at Hawthorne and Torrance boulevards. Police said she still had the cellphone in her hand and her baby in her lap. Police say Bowen claimed the baby was crying.

"To help soothe the 1-year-old, she decided to pull her up to the front seat and try to calm her down," D'Anjou said.

He said officers also found a 2-year-old boy in an unsecured car seat and a 4-year-old girl who was not wearing a seat belt.
