LOS ANGELES (AP) - An illegal immigrant who sought sanctuary in a Chicago church to avoid deportation has been arrested in Los Angeles. That word came this evening from the pastor of the Adalberto United Methodist Church in Chicago where Elvira Arellano (el-VEE'-ruh ah-ray-AH'-noh) had sought sanctuary. The Reverend Walter Coleman says he was with Arellano when she was detained this afternoon. But he says he couldn't immediately provide other details.
