Police arrested a 24-year-old Ground Self-Defense Force private Monday under the antistalking law on suspicion of harassing his 21-year-old former girlfriend in Fukuoka.

Pfc. Taiki Tomita, from the GSDF station in Beppu, Oita Prefecture, was arrested specifically for harassing her by e-mail over three days starting on Nov. 28. Some of the messages warned: "Respond to my e-mail or phone calls or I will go and see you."

Monday's arrest came after Tomita ignored two police warnings against contacting the woman since she broke up with him in September last year. He has been accused of violating the antistalking law, which took effect Nov. 24.
