A few minor sightings in the 2nd season of A Certain Scientific Railgun -
Episode #2: a punk holds a girl's arms behind her back (oops, forgot to note the run time)
Episode #9: girl handcuffed, arms behind (17:30 point)
Episode #24: girl handcuffed, arms in front (best view starting around the 12:30 point)
In every case it's the same girl in the same lab coat.
