He then took the El Cajon resident to the Fiesta Island area of MissionBay, where he sexually assaulted her and held her captive for several hours,the sergeant alleged. About 4 p.m., Lascelles drove to Alpine and dropped theteenager off at the home of one of her relatives, White said.

After being freed, the girl immediately reported the purported crimes.

Early Tuesday afternoon, members of a fugitive task force caught up withthe suspect at a business in the 1200 block of Imperial Avenue in the EastVillage district of downtown San Diego and took him into custody withoutincident.
