The trail of actress Noriko Sakai, who has been missing since her husband was arrested Monday for allegedly possessing illegal stimulant drugs, went cold Tuesday evening in Yamanashi Prefecture, police said Wednesday.

Following a request earlier Tuesday from her mother-in-law to search for the 38-year-old actress, the police traced her cell phone to Yamanashi before the signal stopped, the Metropolitan Police Department said.

Her husband, Yuichi Takaso, 41, was arrested early Monday after a police officer found a plastic bag containing stimulant drugs in his underwear in Tokyo's Shibuya district.

Sakai, who married the self-described professional surfer in 1998, is believed to have disappeared with their child, according to the police.
