ANCHORAGE, Alaska (AP) -- Alaska State Troopers say they have detained a man suspected of stealing women's underwear during burglaries in Kodiak. KTUU-TV reports an 18-year-old was taken into custody Monday. Online court records early Tuesday didn't indicate he had been formally charged. Troopers say the burglaries occurred over three months. Residents would return home to find items -- mostly women's underwear -- missing. They had been alerted to keep their doors locked. The agency says the 18-year-old is suspected of breaking into seven homes and trying to get into three others. Officers called to investigate a report of a home invasion at 11:18 a.m. Monday saw a man running away. They learned the identity of a possible suspect, confirmed a description of his car and made an arrest.
