Police look for clues in Mumbai attacks

Investigators still have no solid leads

MUMBAI, India - Investigators were examining forensic evidence and footage from closed circuit cameras on Friday for clues about who orchestrated the triple bomb blasts that shook India's business hub of Mumbai and killed 18.

Investigators have refused to speculate on who might be behind Wednesday's blasts - in contrast to the 2008 siege in Mumbai, when India swiftly accused Pakistan-based Islamist militants after capturing one of the gunmen.
