KYOTO (Kyodo) A Kyoto University Hospital doctor was arrested Wednesday on suspicion of lacing a female graduate student's tea with sleeping powder, police said.

Manabu Sasahara, a 31-year-old eye doctor from Kyoto, allegedly mixed sleeping powder into a can of tea on the student's desk at a university laboratory around 9 p.m. on March 27, the police said.

The student, 32, also from Kyoto, fainted while eating at a restaurant later, the police said.

The student reported the incident to the maker of the beverage, complaining of something white inside the can, which the maker concluded was sleeping powder.

Sasahara turned himself in to police Wednesday after the incident sparked outrage.

The police quoted Sasahara as saying he was fond of the student and wanted to attract her attention.
