A West High School coach arrested for allegedly handcuffing and tying up teen girls at his home and on campus has been banned from the school.

Michael Anthony Smith, 51, was arrested last week for allegedly tying up four 13- to 17-year-old girls on separate occasions during the past 18 months. There was no indication sex acts occurred.

Smith put tape over the girls' mouths, taped up their hands and feet and handcuffed them, Det. Dave Crespin of the Torrance Police Department said.

Smith, described as a walk-on coach at West High, was released on $50,000 bail after he was booked into jail Dec. 7 for investigation of false imprisonment, annoying children and sexual battery.

School district officials barred him from returning to the campus.
